Hello. I'd like to be able to print variable strings which contain "\" as-is,
without interpreting (for example) "abcde\nuvxyz" as having an embedded newline
(or whatever other escaped instruction).
To do this, I've tried gsub, and here's some of my output (I've tried all kinds
of variations to the arguments):
> message(gsub("[\\]","\\\\","dsff\nfsd"))
dsff
fsd
but I would like to see:
dsff\nfsd
(which is the output of message("dsff\\nfsd") )
I don't know why gsub doesn't accomplish this substitution. How can I replace
(for example), a "\" with "\\"? Any suggestions would be greatly appreciated.
(I know I can use another language, or use inelegant brute force by writing a
new routine which cycles through each possible character that could follow the
single "\".) Watching the gsub echo at the R prompt shows that it is gsub (and
not message) not behaving as I expected.
Other information which the posting guidelines say might help:
