Hi,
I have about 900 files that I need to run the same R script on. I looked
over the R Data Import/Export Manual and couldn't come up with a way to
read in a sequence of files.
The files all have unique names and are in the same directory. What I want
to do is:
1) Create a list of the file names in the directory (this is really what I
need help with)
2) For each item in the list...
a) open the file with read.table
b) perform some analysis
c) append some results to an array or save them to another file
3) Next File
My initial instinct is to use Python to rename all the files with numbers
1:900 and then read them all, but the file names contain some information
that I would like to keep intact and having to keep a separate database of
original names and numbers seems inefficient. Is there a way to have R read
all the files in a directory one at a time?
