[R] How to join path with arguments

[Prof Brian Ripley]

Please just use file.path(inputdir, filename).

Apart from being less error-prone, in R 2.7.0 it will be internal and so 
faster (and in case you wonder how paste could be too slow, it was in some 
of the package installation/checking computations).
