![]() Characters represented by wildcard characters in TargetMask will be identical to the corresponding characters in SourceMask.You cannot specify a new or different drive or path for TargetMask - use the MOVE command instead. ![]() REN SourceMask TargetMaskīoth the SourceMask and TargetMask can contain * and/or ? wildcards.Īs described below, the behavior of these wildcards is slightly different for a source or a target mask. There are doubtless other (likely even better) ways to do this in R, so how would you do it? One candidate might, for example, be file.path() however, I found paste0() to work a little more exactly in what I wanted.Rename a file or files. We can remove the old files with the file.remove()function. There is no Ctrl + Z on deleting files in R! That’s why I like to copy our files to a new location before deleting the source. One nice thing is that because the original files are named sequentially (i.e., DSCN7155 comes before DSCN7156, etc.), so will our new files (i.e., they become ledges_1, ledges_2, etc.). ![]() Now we can open and see that these have more user-friendly names. TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE ![]() A TRUEoutput indicates a successful transfer. Now all we’ll do is copy the files from the old file locations to the new. "C:/LedgesR/ledges_7.JPG" "C:/LedgesR/ledges_8.JPG" "C:/LedgesR/ledges_9.JPG" "C:/LedgesR/ledges_4.JPG" "C:/LedgesR/ledges_5.JPG" "C:/LedgesR/ledges_6.JPG" "C:/LedgesR/ledges_1.JPG" "C:/LedgesR/ledges_2.JPG" "C:/LedgesR/ledges_3.JPG" I have saved these in the folder C:/LedgesR. Using 1:length(old_files)gives us a vector of the exact same length as old_files. For example, instead of DSCN7155.JPG, I want a file name like ledges_1.JPG. Now we can name all the new files that we want. Too bad that vector.files() doesn’t quite have the same ring! > old_files old_files This will make a big difference later on. Using the list.files()function, I see them all “listed.”Īctually, this is a vector, not a list, which is its own thing in R. I have saved these photos under C:/Ledgeson my computer. To rename the files, we will simply list all the current files, list the names of the new files that we want, then switch them around. I thought that this would be a loop and even an apply() function, but it turns out all that’s needed is a list of the file names. Ready to “automate the boring stuff with R?” Check out my course, R Explained for Excel Users. While it was cool to learn for this post that DSCN stands for “Digital Still Capture – Nikon,” it means nothing to me!įor this post, I will be renaming the files that I took from Worden Ledges into a more “human-readable” name. I hate the way files are run in a camera.
