Re: [R] regexp inside and outside brackets

It depends the complexity of your expression. If you are sure you don’t have nested brackets, and pairs of brackets always match, this will take everything outside the brackets: str <- "A1{0}~B0{1} CO{a2}NN{12}” gsub("\\{[^}]*\\}", " ", str) Philippe Grosjean > On 11 Dec 2015, at 14:50,

Re: [R] there is a vectorinzing version of "[[<-" for "tclArray" class ?

library(tcltk) methods(class = "tclArray") ## [1] [[ [[<- $$<- length length<- namesnames<- ## see '?methods' for accessing help and source code It should be something like `[<-`. But this one is not defined. Perhaps can you contribute one here? Best, Philippe

Re: [R] column means dropping column minimum

There is a bug in your code: it is not > for (i in 1:ncol(test)) { test2[which.min(test[,i]),i]==NA} but for (i in 1:ncos(test)) { test2[which.min(test[, i]), i] <- NA } Otherwise, a solution would be to create your own function to compute the mean of a vector without the smallest value:

Are you sure this is the right way to go for your use case? Even if you got a quick solution to display an 1e4 x 100 table in TkTable, what is the purpose of it? Will the user browse the whole dataset that way? Even if the answer is yes, you would probably need to implement sorting and

Re: [R] Tktable do not expand inside a Tkframe

Instead of using tkgrid(), you can do this with tkpack(). Replace: > tkgrid( tableData, scrY ) > tkgrid.configure( scrY, sticky="nsw") > tkgrid( scrX, sticky="new" ) by: scrYwidth <- as.integer(tkcget(scrY, width = NULL)) tkpack(scrY, side = "right", fill = "y", expand = FALSE, pady = c(0,

Re: [R] Passing variable names in quotes to a function

Your example and explanation are not complete, but I have the gut feeling that you could do all this both more efficiently *and* more R-ish. First of all, why would you pass Y and X separately, to ultimately build the Y ~ X formula within the body of your function? Secondly, it seems to me

Re: [R] One application of Tcltk2

Hello, tk2notebook() is a ttk/tile styled widget. Its appearance is governed by styles. Before you change style, you should first look if there is one predefined theme that better suits you: tk2theme.list() # List all available themes [1] clamalt default classic tk2theme(clam) # Change
