Have you tried a different mirror? If they all fail, also check your internet
connection.

Yes.
sub() replaces substrings. The first argument captures the interesting part of
the string:
^ = start of the string,
([0-9
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 that

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, s
It depends what property you are looking for… Have you tried tkcget(table, …)?

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 filtering
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?

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)

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] "clam""alt" "default" "classic"
> tk2theme("clam
12 matches
