Reading in multiple files
I apologize if this is a FAQ -- I kind of recall seeing something along
these lines before, but I couldn't find the message when I searched the
archives.
Problem:
1. I have hundreds of small files in a subdirectory ("c:\\temp") and I would
like to combine the files into a single data frame.
2. Individually, it is easy to read each file
DATA<-read.csv("c:\\temp\\file1a.csv",header=T)
3. It is also fairly easy to add new files to the data frame one at a time:
DATA<-rbind(DATA,read.csv("c:\\temp\\file1b.csv",header=T))
What is tedious about this solution is that we have to change the file name in step 3 every time. Is there a way to have R identify all the files in a directory and create one big data frame? I'm working in Windows with R 1.6.2. Thanks Paul MAJ Paul Bliese, Ph.D. Walter Reed Army Institute of Research Phone: (301) 319-9873 Fax: (301) 319-9484 paul.bliese at na.amedd.army.mil
