[R] how to input multiple .txt files

[Mike Lawrence]

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(path=path_to_my_files,pattern='cust2',full.names=TRUE)
a=NULL
for(this_file in cust2_files){
       a=rbind(a,read.table(this_file))
}
write.table(a,'cust2.master.txt')
