problem for strsplit function
Hello, I would suggest something like `tools::file_path_sans_ext` instead of `strsplit` to remove the file extension. This is also vectorized, so you won't have to use a `sapply` or `vapply` on it. I hope this helps! On Wed, Jul 7, 2021 at 9:28 PM Kai Yang via R-help <r-help at r-project.org> wrote:
Hello List,
I have a one column data frame to store file name with extension. I want
to create new column to keep file name only without extension.
I tried to use strsplit("name1.csv", "\\.")[[1]] to do that, but it just
retain the first row only and it is a vector. how can do this for all of
rows and put it into a new column?
thank you,
Kai
