you can extract numbers from your file names and then sort them like this:
filelist = list.files(pattern = ".s*.txt")
filelist[order(as.integer(gsub("[^0-9]", "", filelist)))]
(cf with alphabetic order: filelist[order(gsub("[^0-9]", "", filelist))]
Or if you just have s1...s120 you can construct the names programmatically
filelist<-paste0("s", 1:120, ".txt")
