R help - Oct 2006 - multiline string continuation

Dear R experts,

I wonder how can one input a string variable in multiple lines in a R
script. I've seen solution to the command line continuation in the
non-string situation (just continute at the new line). However, that
doesn't work for strings because the new line character, "\n", is
included in the resultant string. For example, if I type the following
in a script:

datadir=" X:/level1/level2
/level3/level4/
level5/level6"

after executing the script, string variable "datadir" becomes

"X:/level1/level2\n/level3/level4/\nlevel5/level6"

Someone has suggested to use "paste()" for putting pieces of strings
together, but I would like to see if there is any other simpler
workaround for multiline string continuation.

Best,

Erik

maybe you're looking for:

cat(datadir)


I hope it helps.
