Thank you very much for all of the help!!! For what I need, Jim's and
Jeff's solutions were the most useful, but I really appreciate all of the
help I got.

Try this:
# install package HelpersMG from CRAN including dependencies
install.packages("HelpersMG")
# Update to the lastest version
install.packages("http://www.ese.u-psud.fr/epc/conservation/CRAN/HelpersMG.tar.gz";,
repos=NULL, type="source")
# Use the function read_folder()

Computing filenames is a dangerous, backwards approach. If you already _have_
files, it's wrong to create filenames from assumptions. Rather you need to
capture the existing filenames with an appropriate use of list.files(), and
then process that vector. Computing filenames only has a place when
I tried the following but it does not work:

I tried that and R comp
Normally one wants not only to read the data, but to save it in an object
as well. Here are some modifications toward achieving that (untested):
header<-"C:/Research3/simulation1/second_gen/pheno_1000ind_4000m_add_h70_prog"
fnums <- expand.grid( a = 1:2, b = 2:3 )
result <- vector( "list", nrow(
Hi Reka,
Try this:
header<-"C:/Research3/simulation1/second_gen/pheno_
1000ind_4000m_add_h70_prog"
for(index1 in 1:2) {
for(index2 in 2:3)
read.csv(paste(paste(header,index1,index2,sep="_"),".csv",sep=""))
}

Hello,
I have over 1000 csv data sets I need to read into R, so I want to read
them in using a loop. The data sets are named as
pheno_1000ind_4000m_add_h70_prog_1_2.csv,
pheno_1000ind_4000m_add_h70_prog_1_3.csv, ... so I need 2 loops (for the
last 2 numbers in the names). What I would like to do is
