Hi, looks like the list.files() method was the key to my problem. With
that, I was able to just loop through the "files" variable and get the
file names to load
Thanks for your help.

Something like the following might work. YOu can use 'choose.dir()'
to get the directory:
files <- list.files(path=yourDir)
result <- do.call(rbind, lapply(files, read.csv))

Hi,
I am trying to load csv type data from a folder. However, rather than
syntax that simply loads one file at a time I was wondering if there
is a method that loads all data from a specific folder.
For instance, I have the following data files in a folder
nebraskaStats:
10-1-2009_10-7-2009.txt
10-2-2009_10-8-2009.txt
10-3-2009_10-9-2009.txt
....etc. (245 total files in folder)
Each file has the following format:
Data1-5,Data 2-6,Data 3-7,...
1,2,3,...
Although the comma separated format is consistent file to file, the
name of the columns differ in many of the files.
What I want to do is simply load all that data by pointing to the
folder rather than specific file names.
I know this syntax: state.frame<-read.table("/nebraskaStats/",
header=T, sep=",") does not seem to read data from a folder but
rather
it is intended to load specific files. I could write a loop that
iterates the number of the files (e.g., N-S-2009_N-T-2009, whereby
N,S, and T are iterated in the loop); however, this also seems
cumbersome. Anyway, is there a simple method that just loads all the
data in a folder rather than have to call out each specific file?
Thanks in advance. This has been a great board and I appreciate all
the past help.
