[R] Is there string class in R?

[Michaell Taylor]

There are lots of ways you could approach this:

files _ list.files('.')
files _ files[grep('.PRN$',files)]
for (File in files){
	scan(file=File)
	....
}

would provide lots of flexibility - grep could be used to specify 'irregular' 
types of file names.

If you have very structured file names, then your example would be great.

for i in 1:20
{
   filename = paste("***",i,+".PRN",sep='')
   scan(file=filename)
   ....
}
