Using Brackets in MathJax - Tree Question - mathjax

I have used LaTeX using different packages to make trees, e.g. using the format below. Is there a way to get a tree to run using MathJax using the code below? I have a bunch of trees that I coded using the exact format below, and I am wanting to get them online. What would I have to do for the program to recognize the 'forest'? Is there something minor that I could adjust to get it to work?
\begin{forest}
for tree={l+=0.5cm} % increase level distance
[,roof
[1[2[3[4]][4[3]]][3[2[4]][4[2]]][4[2[3]][3[2]]]]
[2[1[3[4]][4[3]]][3[1[4]][4[1]]][4[1[3]][3[1]]]]
[3[1[2[4]][4[1]]][2[1[4]][4[1]]][4[1[2]][2[1]]]]
[4[1[2[3]][3[2]]][2[1[3]][3[1]]][3[1[2]][2[1]]]]
]
\end{forest}

What the function of checking graph's length(weight) between two nodes in networkx?

I make a Graph by networkx, and it is like that:
now I want to check the distance(weight) between two points, for example point 6 and 7?
Is there some simple syntax can search it like, Graph[6][7]['length']?
You can try this package
https://pypi.org/project/graph-theory/
Check the gd3.distance(n1,n2)

Print a variable with index (eg. x_1)

i am trying to print variables with indices.
The goal is to write something like:
x_1 + x_2 = 3 + 1 = 4
The problem is, that variables just like x_1 does not show an index. It shows the underscore itself.
/* works fine */
print(x_1)$
x_1;
/* Does not work */
ostream: make_string_output_stream()$
printf(ostream, string(x_1))$
get_output_stream_string(ostream);
Output of the code above
Converting "x_1" into a string destroys the underscore, but you need a string for the method printf().
Are there workarounds for this?
What to do here probably depends somewhat on what goal you need to achieve with this. Can you say more about the larger goal you are working toward?
In order to generate output which has typesetting instructions in it, you can call the tex or tex1 function to generate TeX output. If that needs to be displayed in a web page, I believe you can make use of the MathJax Javascript library. Sorry, I don't know more about MathJax.
You should probably write x[1] instead of x_1. Displaying x_1 with a subscript 1 is a convenience -- the rest of Maxima doesn't know much about it.
EDIT: There is also an add-on package to output MathML; there might be two such packages, I would have to check. If MathML could help solve your problem, I will look into it.

how to plot a graph using haskell graphViz

I'm planning to draw a graph using Haskell graphViz. I'm new to haskell, so this is quite difficult for me. Can someone show me a simple example ? I need a very simple example actually, so that I can understand it and use it in the scenario I'm working on
I get the above error on trying to install chart-cairo. I saw some examples on the internet and all of them requires chart-cairo. any idea how to resolve it ?
*EDITED"
The output that I get after executing the code given by https://stackoverflow.com/users/2827654/jamshidh
(This addresses your original question, described in the title, and doesn't go into the problems installing chart-cairo or chart, etc, which really should be spun out into different questions)....
The graphviz package includes some example graphs in module Data.Graph.Inductive.Example that can be used to get you up and running. You can see the list of included graphs at http://hackage.haskell.org/package/fgl-5.3/docs/Data-Graph-Inductive-Example.html.... I will use one called clr479.
Once you have a graph, you can convert it to an internal structure representing the dot format using graphToDot. Note that you will need to supply some parameters, which are described in http://hackage.haskell.org/package/graphviz-2999.11.0.0/docs/Data-GraphViz.html. Just to get up and running, I will use the supplied nonClusteredParams.
let graphInDotFormat = graphToDot nonClusteredParams clr479
Then, you will need to convert this to text suitable for input to the dot program. You can do this with renderDot . toDot
let outputText = renderDot $ toDot graphInDotFormat
and, as usual, you need to convert text to string to use putStrLn (don't just use show, as it will include quotes and escape sequences, which dot will not understand)
putStrLn $ unpack outputText
Putting this all together, the final program createDotFile.hs would be
import Data.Text.Lazy
import Data.GraphViz
import Data.Graph.Inductive.Example
import Data.GraphViz.Printing
main = putStrLn $ unpack $ renderDot $ toDot $ graphToDot nonClusteredParams clr479
Compile using ghc createDotFile.hs (remember to cabal install the required packages, as well as graphviz itself if you want to do anything with the output). On the commandline, you can now pipe the output of this program to dot, which will convert this to a usual format.... For instance, here I convert to svg
./createDotFile | dot -Tsvg > graph.svg
which on my linux box can be viewed by typing
eog graph.svg
Edit-
To clarify, the output of the haskell program needs to be provided as an input to GraphViz. The msi file to install graphviz on windows here http://www.graphviz.org/Download_windows.php.

How to number floats in LaTeX consistently?

I have a LaTeX document where I'd like the numbering of floats (tables and figures) to be in one numeric sequence from 1 to x rather than two sequences according to their type. I'm not using lists of figures or tables either and do not need to.
My documentclass is report and typically my floats have captions like this:
\caption{Breakdown of visualisations created.}
\label{tab:Visualisation_By_Types}
A quick way to do it is to put \addtocounter{table}{1} after each figure, and \addtocounter{figure}{1} after each table.
It's not pretty, and on a longer document you'd probably want to either include that in your style sheet or template, or go with cristobalito's solution of linking the counters.
The differences between the figure and table environments are very minor -- little more than them using different counters, and being maintained in separate sequences.
That is, there's nothing stopping you putting your {tabular} environments in a {figure}, or your graphics in a {table}, which would mean that they'd end up in the same sequence. The problem with this case (as Joseph Wright notes) is that you'd have to adjust the \caption, so that doesn't work perfectly.
Try the following, in the preamble:
\makeatletter
\newcounter{unisequence}
\def\ucaption{%
\ifx\#captype\#undefined
\#latex#error{\noexpand\ucaption outside float}\#ehd
\expandafter\#gobble
\else
\refstepcounter{unisequence}% <-- the only change from default \caption
\expandafter\#firstofone
\fi
{\#dblarg{\#caption\#captype}}%
}
\def\thetable{\#arabic\c#unisequence}
\def\thefigure{\#arabic\c#unisequence}
\makeatother
Then use \ucaption in your tables and figures, instead of \caption (change the name ad lib). If you want to use this same sequence in other environments (say, listings?), then define \the<foo> the same way.
My earlier attempt at this is in fact completely broken, as the OP spotted: the getting-the-lof-wrong is, instead of being trivial and only fiddly to fix, absolutely fundamental (ho, hum).
(For the afficionados, it comes about because \advance commands are processed in TeX's gut, but the content of the .lof, .lot, and .aux files is fixed in TeX's mouth, at expansion time, thus what was written to the files was whatever random value \#tempcnta had at the point \caption was called, ignoring the \advance calculations, which were then dutifully written to the file, and then ignored. Doh: how long have I know this but never internalised it!?)
Dutiful retention of earlier attempt (on the grounds that it may be instructively wrong):
No problem: try putting the following in the preamble:
\makeatletter
\def\tableandfigurenum{\#tempcnta=0
\advance\#tempcnta\c#figure
\advance\#tempcnta\c#table
\#arabic\#tempcnta}
\let\thetable\tableandfigurenum
\let\thefigure\tableandfigurenum
\makeatother
...and then use the {table} and {figure} environments as normal. The captions will have the correct 'Table/Figure' text, but they'll share a single numbering sequence.
Note that this example gets the numbers wrong in the listoffigures/listoftables, but (a) you say you don't care about that, (b) it's fixable, though probably mildly fiddly, and (c) life is hard!
I can't remember the syntax, but you're essentially looking for counters. Have a look here, under the custom floats section. Assign the counters for both tables and figures to the same thing and it should work.
I'd just use one type of float (let's say 'figure'), then use the caption package to remove the automatically added "Figure" text from the caption and deal with it by hand.

How can I find all R packages that include graphics functions?

I always have difficulty in finding all available alternative ways to produce a specific graph, either one that I have already decided to use (looking for different variations) or one that I have not yet thought of.
The R Graphical Manual site provides a complete list of samples of R's graphics functions, however it's easier for me to search providing a package name (how else -for example- can I get a resultset including superbarplot function, when I want to look for barplots?. Let alone that the superbarplot graph does not appear in the results even if I try searching for it's package: UsingR)
The R-SAS-SPSS Add-on Module Comparison - and especially on topic Graphics, Static in the table provided - gave me the idea that it would be nice to have a place where all relevant packages are listed by topic.
Do you have any idea about something like that?
If you're interested in learning about all the possible graphics you can make, you should learn about the grammar of graphics, and (my) implementation of it in R: ggplot2.
Your question, or the general pattern anyway, was clearly a primary use case for the design of the sos package.
sos actually goes one step further that your question requires by identifying particular functions with packages; in addition, it ranks the results by relevance (by default, you can change the default behavior via the "sortby" parameter, e.g., sortby="Date")
Here's how it works:
most of this package's functionality is exposed via the "findFn" command
for instance, if you want a list of all functions and the parent package related to scatter plots:
findFn("scatter plot", maxPages=2, sortby="TotalScore")
This returns a dataframe formatted as HTML table and delivered in your default browser (if you don't want it to pop-up immediately, then just bind the function call to a variable and then call the variable when you're ready)
The right-most column of the dataframe/HTML page is "Description and Link". Clicking an entry in that column opens another tab in your browser (according to the user-set preferences set in your browser) with the complete R help page for that function.
The results from the function call above show, for instance, that the functions for plotting data in a 'scatter plot' format are found in the following packages:
ade4 (function: scatter)
IDPmisc (functions: ipairs, iplots)
GGally (function: ggally_points)
PerformanceAnalytics (function:
chart.Scatter)
mclust (function: clPairs)
Another example:
findFn("boxplot", maxPages=2, sortby="TotalScore")
identifies these (among others) packages/functions for plotting boxplots:
sfsmisc (function: boxplot.matrix)
aplpack (function: boxplot2D)
NADA (function: boxplot-methods)
StatDA (function: rg.boxplot)
plotrix (function: gap.boxplot)
gplots (function: boxplot.n)
multcompView (function:
multcompBoxplot)
oligo (function: boxplot)
Have you seen the R Graph Gallery ?
Other than that, you may have to index all the source code of CRAN packages to search efficiently...
these are good memory-joggers. I second the ggplot2 recommend, also recommend looking thru CRAN views:

http://cran.fhcrc.org/web/views/Graphics.html
