Actually I find a hard-coded path *especially* useful when I'm using
more than one computer as it reminds me of what directory I'm suppose to
be working in.
I write code like
wbf = #"C:\\Files\\Consulting\\Cilla\\Wetaboxes 1.7.09.csv"
longterm = read.csv(wbf,header=TRUE)
and move the # around depending on what computer I'm on.
