This is a follow up to a question that I had before. I know about the DoRectFloat/RationalRect modules and such, but, I've tried to write proper Haskell and it either doesn't compile, or it compiles and doesn't do what I want.
(These are floating windows that I want) What I want is a layout like
How would I go about writing this?

When starting the three windows, use xterm's -class option to modify the WM_CLASS property it attaches to its window, choosing a different and unique class for each of the three. Then you can select for that class in your manage hook to only match the right window.
I'm using GNU Screen to send code from Vim to R with the following .vimrc configuration:
map <C-L> "kyy:echo system("screen -S $STY -p R -X stuff ".shellescape(#k))<CR>j
vmap <C-L> "xy:echo system("screen -S $STY -p R -X stuff ".shellescape(#x."\n"))<CR>j
(I use cntr-L to send code from Vim to my R window titled "R".)
I can run functions within the current screen,
exp_val <- function(roll){
vals <- numeric(length(roll))
vals[roll == "G"] <- 1/6
vals[roll == "Y"] <- 1/3
vals[roll == "R"] <- 1/2
sum(vals)
}
prob_choice <- function(roll, ng = 6, ny = 4, nr = 3){
tot <- ng + ny + nr
i <- c(ng,ny,nr)
col <- c("G","Y","R")
p1 <- i[col==roll[1]]/tot
i[col==roll[1]] <- i[col==roll[1]] - 1
p2 <- i[col==roll[2]]/(tot-1)
i[col==roll[2]] <- i[col==roll[2]] - 1
p3 <- i[col==roll[3]]/(tot-2)
p1*p2*p3
}
but when I try to scroll down and highlight another function that extends below the original screen view
single_round <- function(sampsp,probs=rep(1/nrow(sampsp),nrow(sampsp))){
r <- sample(1:nrow(sampsp),1,prob = probs)
dice <- sampsp[r,]
roll <- numeric(3)
i <- which(dice=="G"); roll[i] <- sample(c("B","S","F"),1,prob = c(1/2,1/6,1/3))
j <- which(dice=="Y"); roll[j] <- sample(c("B","S","F"),1,prob = c(1/3,1/3,1/3))
k <- which(dice=="R"); roll[k] <- sample(c("B","S","F"),1,prob = c(1/6,1/2,1/3))
num_dice <- c(length(i),length(j),length(k))
outcome <- c(sum(roll=="B"),sum(roll=="S"),sum(roll=="F"))
if (is.null(roll[i])){roll[i] <- 0}
if (is.null(roll[j])){roll[j] <- 0}
if (is.null(roll[k])){roll[k] <- 0}
feet <- c(sum(roll[i]=="F"),sum(roll[j]=="F"),sum(roll[k]=="F")) # to keep track of color of footprints
list(num_dice,outcome,feet)
}
I get the following error
X: stuff: one or two arguments required
Is there anything I can change in my .vimrc so I can highlight and execute a large part of the script that extends beyond the original screen view?
I'm sure this is simple, but I cannot find a solution ...
I would like to use a variable containing a character string as argument for a function.
x <- c(1:10)
myoptions <- "trim=0, na.rm=FALSE"
Now, something like
foo <- mean(x, myoptions)
should be the same as
foo <- mean(x, trim=0, na.rm=FALSE)
Thanks in advance!
You can use eval and parse:
foo <- eval(parse(text = paste("mean(x,", myoptions, ")")))
A more natural way to do what you want is to use do.call. For example,
R> l[["trim"]] = 0
R> l[["na.rm"]] = FALSE
R> l[["x"]] = 1:10
##Or l <- list(trim = 0, na.rm = FALSE, x = 1:10)
R> do.call(mean, l)
[1] 5.5
If for some reason you really want to use a myoptions string, you could always use strsplit to coarce it into a list form. For example,
R> y = "trim=0, na.rm=FALSE"
R> strsplit(y, ", ")
[[1]]
[1] "trim=0" "na.rm=FALSE"
R> strsplit(y, ", ")[[1]][1]
[1] "trim=0"
Here's a third answer that both uses parse, alist and do.call. My motivation for this new answer, is in the case where arguments are passed interactively from a client-side as chars. Then I guess, there is no good way around not using parse. Suggested solution with strsplit, cannot understand the context whether a comma , means next argument or next argument within an argument. strsplit does not understand context as strsplit is not a parser.
here arguments can be passed as "a=c(2,4), b=3,5" or list("c(a=(2,4)","b=3","5")
#' convert and evaluate a list of char args to a list of arguments
#'
#' #param listOfCharArgs a list of chars
#'
#' #return
#' #export
#'
#' #examples
#' myCharArgs = list('x=c(1:3,NA)',"trim=0","TRUE")
#' myArgs = callMeMaybe(myCharArgs)
#' do.call(mean,myArgs)
callMeMaybe2 = function(listOfCharArgs) {
CharArgs = unlist(listOfCharArgs)
if(is.null(CharArgs)) return(alist())
.out = eval(parse(text = paste0("alist(",
paste(parse(text=CharArgs),collapse = ","),")")))
}
myCharArgs = list('x=c(1:3,NA)',"trim=0","TRUE")
myArgs = callMeMaybe2(myCharArgs)
do.call(mean,myArgs)
[1] 2
Using all of do.call, eval and parse (combining kohske's and csgillespie's answers, and also WoDoSc's answer to 'Pass a comma separated string as a list'):
x <- c(1:10)
myoptions <- "trim = 0, na.rm = FALSE"
do.call(
what = mean,
args = append(list(x = x), eval(parse(text = paste0("list(", myoptions, ")"))))
)
This solution can be quite resilient in a more complex case, such as shown below.
myfn <- function(x, y = 0, z = 0, ...) {
print(paste("x:", x))
print(paste("y:", y))
print(paste("z:", z))
if (length(list(...)) > 0) {
print("other:")
print(list(...))
}
}
myextraargs <- paste(
"y = c(11, 14), z = 47,",
"t = data.frame(p = c('apple', 'plum'), j = c(7, 2), k = c(3, 21))"
)
do.call(
what = myfn,
args = append(
list(x = 7),
eval(parse(text = paste0("list(", myextraargs, ")")))
)
)
results in:
[1] "x: 7"
[1] "y: 11" "y: 14"
[1] "z: 47"
[1] "other:"
$t
p j k
1 apple 7 3
2 plum 2 21
...and...
myextraargs <- NULL
do.call(
what = myfn,
args = append(
list(x = 7),
eval(parse(text = paste0("list(", myextraargs, ")")))
)
)
results in
[1] "x: 7"
[1] "y: 0"
[1] "z: 0"
