Hi R users, I have a question about opening the txt files and putting them into a matrix. The txt files are in the folder01, while they have the name file.1.txt, file.2.txt, file.3.txt, etc. There are about 200 such text files. Each txt file contains one value inside. When I tried to use the code below, I found that the txt files are not in order, from 1, 2, 3, to 200. Rather, they are in the order 1, 10, 100, 101, etc. How to change it so that they are in order? Thanks for your help.
temp <- list.files('folder01',pattern="*.txt" name.list <-lapply(paste('folder01',temp,sep='/'),read.table,head=F) library(data.table) files.matrix <-rbindlist(name.list) Also, when use the code below, how to complete it so that the values of the files are stored in a matrix? lists = list.files('folder01') for (i in 1:length(lists)){ file <- read.table(paste('folder01',lists[i],sep='/'),head=F) print(file) } [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
