Hi,
I think it is not possible in R but I rather ask before giving up:
What I have: I have copied "C:\Program Files\R" into my clipboard.
What I want: setwd(transform("C:\Program Files\R")) where the function
transform should change the "C:\Program Files\R" from my clipboard to
"C:\\Program Files\\R" so that R can handle it. Is this possible?
I've tried with gsub("\\", "\\\\", "C:\Program
Files\R") but failed, then
tried first to split the full clipboard string cause \P is reserved in R but
with strsplit("C:\Program Files\R", "") I also failed.
Therefore the question: It is really necessary to manually add a second
"\"
in "C:\Program Files\R", so that setwd("C:\\Program
Files\\R") can change my
work directory?
Cause I am getting tired making this manually... yes I know I can use the
Search&Replace function from the Editor but I thought R can do everything?
I hope someone could help me :(

Interesting question. It is really about how to avoid the interpretation of \ as
an escape character in a string. I wonder if it is possible.
Anyway, have you tried the following:
setwd(readLines("clipboard",warn=F))
"clipboard" is a special filename that tells R to read from the
clipboard.

Is this possible?No, but you shouldn't be doing that. You should read the string from the clipboard as a string, not as R code, because it's a string, not R code. For example, if your clipboard contains that string, dir <- readClipboard() setwd(dir)> I've tried with gsub("\\", "\\\\", "C:\Program Files\R") but failed, then > tried first to split the full clipboard string cause \P is reserved in R but > with strsplit("C:\Program Files\R", "") I also failed. > > Therefore the question: It is really necessary to manually add a second "\" > in "C:\Program Files\R", so that setwd("C:\\Program Files\\R") can change my > work directory?No. You only want a single backslash in the string. The problem is that you are using the parser: to get the parser to create a string with a single backslash in it, you need to give two to the parser. So don't use the parser.
