To get the file names in the current directory try:

list.files(pattern="[[:digit:]]{7}E")

[R] for loop looking for file names

2008-12-02 Thread Steven Kennedy

I have a series of csv files in several folders. All begin with a 7 digit
number and end with the letter "E" (eg. 0726016E.csv).

I want to be able to read a file in to R, take some of the data out of it
and store it in a matrix, then move on to the next file and do the same
thing.

I was planning on using a for loop for the digits at the start of the file
name, but I'm not sure how I can append the letter to the end of the number
string.

I'm also open to any ideas other than the for loop.

Thanks,
Steven Kennedy
