[R] Problem compiling Rnw file

[Jessica Streicher]

I'll second the full path option.

Just create a variable path_to_data and concatenate it with the names of any files you need in that directory.
You could also try to use relative paths if the data is "nearby" and is likely to not change that position.

e.g. if the data was in '/home/r/Documents/mydata/whatever.txt', while you are working in '/home/r/Documents/myproj/', you can reach that directory via '../mydata/whatever.txt'.
