You might also want to do
names(cust1_files) <-
To repent for my sins, I'll also suggest that Hadley Wickham's "plyr"
package (http://had.co.nz/plyr/) is also useful/parsimonious in this
context:
a <- ldply(cust1_files,read.table)

may i suggest the following,
a <- do.call(rbind, lapply(cust1_files, read.table))
(i believe expanding objects in a for loop belong to the R Inferno)

oops, didn't read the question fully. If you want to create 2 master files:
cust1_files = list.files(path=path_to_my_files,pattern='cust1',full.names=TRUE)
a=NULL
for(this_file in cust1_files){
a=rbind(a,read.table(this_file))
}
write.table(a,'cust1.master.txt')
cust2_files = list.files(pa
my_files = list.files(path=path_to_my_files,pattern='.txt',full.names=TRUE)
a=NULL
for(this_file in my_files){
a=rbind(a,read.table(this_file))
}
write.table(a,my_new_file_name)

how to input multiple .txt files?
A data folder has lots of .txt files from different customers.
Want to read all these .txt files to different master files:
such as:
cust1.xx.txt, cust1.xxx.txt, cust1..txt,.. to master file:
X.txt
cust2.xx.txt, cust2.xxx.txt, cust2.
