file path
Hmm, I don't think it gives what I want. For example, I assign a file name to f,
f <- "a?b.txt"
file.path("e:",f)
[1] "e:/a?b.txt" The resultant character is not accepted as a file name by Windows OS.

Dear all, is there any function to assert whether a file path is legitimate, and to convert any potential file path to a legitimate file path? I automate a batch of files and write them to plain text files with cat(). The file argument of cat() is generated automatically which may contain characters such as ? < >, unacceptable in Windows OS. What I do at this moment is to strip such characters off with gsub(). Is there any direct way to make legitimate file path without detailed knowledge about the naming rule specific to a OS?
