Something like this has been suggested in R-help before:
files <- dir()
results <- lapply(files, yourprocessing())
The dir function has path and pattern arguments to select the set of
files you want.
This works fine when there are no problems, but often I'll use a for
loop so problem files can be dealt with differently when necessary.
Perhaps something like this:
ProcessList <- dir(pattern="InPerson*")
for (i in 1:length(ProcessList))
Remember to use seq_along() instead: ProcessList might be length 0.

filename <- ProcessList[i]
