I'd do something like this:

[1] "dat.csv"
You put the possible file names into the variable in the order of
preference. E.g. I prefer "dat.csv" over "dat" if by chance both exist.
> files=c('not.csv','not')
> file2read=files[file.exists(files)][1]
> file2read
[1] NA
The above shows the result should none of the files exist. So if
"file2read" has an NA, then you go on to the next directory.
