Reply: The problem with this command is that it produces

paste("c:",  "work", "part1.txt", sep="\\")
[1] "c:\\work\\part1.txt"

whereas I want "c:\work\part1.txt".  Some people have suggested to try
'file.path', but it either doesn't work, or I don't know how to make it
work.

> file.path("c:","work","part1.txt", fsep = "\")
Error: syntax error
> file.path("c:","work","part1.txt", fsep = "\\")
[1] "c:\\work\\part1.txt"
