The code given below worked well. However, the problem is that when I typed dir1 to see the results I found that R order the files as: [1] "data1.flt" "data10.flt" "data100.flt" "data101.flt" [5] "data102.flt" "data103.flt" "data104.flt" "data105.flt" [9] "data106.flt" "data107.flt" "data108.flt" "data109.flt" [13] "data11.flt" "data110.flt" "data111.flt" "data112.flt" [17] "data113.flt" "data114.flt" "data115.flt" "data116.flt" . . to . . [357] "data91.flt" "data92.flt" "data93.flt" "data94.flt" [361] "data95.flt" "data96.flt" "data97.flt" "data98.flt" [365] "data99.flt"
which will lead to wrong results. How to tell R to start reading from 1 to 365 in order. something like : [1] "data1.flt" "data2.flt" "data3.flt" "data4.flt" not like: [1] "data1.flt" "data10.flt" "data100.flt" "data101.flt" Here is the code: dir1<- list.files("C:\\Users\\Amin\\Desktop\\2001", "*.flt", full.names = TRUE) results<- list() for (.files in seq_along(dir1)){ file2 <- readBin(dir2[.files], double(), size = 4, n = w * 67420, signed = TRUE) results[[length(results) + 1L]]<- file1[file1 != -9999]*10} for (i in seq_along(results)){ fileName <- sprintf("C:\\Users\\aalyaari\\Desktop\\New folder (2)\\NewFile%03d.bin", i) writeBin(as.integer(results[[i]]), fileName, size = 2)} -- View this message in context: http://r.789695.n4.nabble.com/Why-R-order-files-as-1-10-100-not-1-2-3-tp4631584.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
