如何使用 R 重命名文件？

Question

I have a bunch of files that have "_001" in their file names. I followed a script posted online and I am at the directory where all my files are located:

filez <- list.files()
sapply(filez, function(X) {file.rename(from=x, to=sub(pattern="_001", replacement="", x))})

But I keep getting this error message:

Error in file.rename(from = x, to = sub(pattern = "001", replacement = "")): object 'x' not found".

Can anyone help me solve this problem?

Answer 1

I don't think you need to do this with sapply at all. (This will bypass the problem you are having where the arguments to file.rename and sub should have been X .) Try this instead:

filez <- list.files()
file.rename(from=filez, to=sub(pattern="_001", replacement="", filez))
