Simpler, but would fail if there are more "."s beyond the second (it
changes the last one to a "-"):

There are many ways, Rolf. You need to look into the syntax of regular
expressions. It depends on how sure you are that the formats are exactly as
needed. Escaping the period with one or more backslashes is one way. Using
string functions is another.
Suggestion. See if you can make a regular expre

I want to deal with strings of the form "a.b.c" and to change (using
sub() or whatever is appropriate) the second "." to a "-", i.e. to
change "a.b.c" to "a.b-c". I want to leave the first "." as-is.
I guess I could do a gsub(), changing all "."s to "-"s, and then do
a sub() changing the first

Hi Jeremie,
Try this:
test <- function() {
a<-readline("selection: ")
return(a)
}
If it starts working, it could be a difference in the way Windows R
handles text input. Both work okay for me on fedora linux.

David,
Is this what you are looking for?

Hello,
I have noticed a behavior that I don't understand. When I call the

I can only type one character and the readline function exits before I can
press enter.

Hi
No attachments allowed (usually).
What do you mean by 3 dimensional list? List itself can contain objects
which could also be lists.
