Delete lines of a text file in R

Question

I have a .xml file that I read with readLines() in R. I would like to know if there is some function that allow me to delete from line 15 to line 18.

I would need of a general command, because I have to repeat the function in loop on the same .xml file, but for the following lines.

Answer 1

readLines creates a character vector where each element is a line from the original file. If you want to remove lines 15 through 18, just remove those elements from the vector.

my_new_file = current_file[-(15:18)]

You can then use writeLines to replace the old file with the edited version.
