[R] Construct a File Path: File Path Unknown

[Brad Patrick Schneid]

it would probably be faster if you can be as specific as possible... in the
help that has been provided, it is looking everywhere in  c:/    

you could narrow that down a bit and save it from looking too deep in your
system.

dir("C:\Documents and Settings\username\Desktop", pattern="foo.pdf",
full.names=T, ignore.case=T, recursive=T)

**I'm not 100% about this, but it seems logical to me
