[R] Extracting File Basename without Extension

[jim holtman]

You can use 'sub' to get rid of the extensions:

> sub("^([^.]*).*", "\\1", 'filename.extension')
[1] "filename"
> sub("^([^.]*).*", "\\1", 'filename.extension.and.more')
[1] "filename"
> sub("^([^.]*).*", "\\1", 'filename without extension')
[1] "filename without extension"
