If you're reading data using scan() or read.table() (or whatever
low-level functions those use), then you don't need to double the
backslash in the datafile.  This means it's easy to read in a long
list of pathnames from a file.

On the other hand, if the backslash appears in R code (which you type
at the command line, or use source() to read), then it passes through
the parser, and the backslash is treated as an escape character.
