cycle <- function(file.path = ".", file.pattern = "*.dat")
files.2.process <- dir(path = file.path, pattern = file.pattern)
for(file.name in files.2.process)
current.file <- read.table(file.name, header = TRUE)
# now do something with this data ...
Does it for me. The file.pattern parameter takes regular expressions.
