taglist plugin does not recognize my ~/.ctags customizations

Dear Vimmers and Taglist experts,

recently I started working on R code. To make ctags work on R files, I
used some customizations saved in a .ctags file in my home dir.

The generation of tags works fine and Vim works well with the tags,
only the Taglist plugin does not recognize the customization. The
Taglist simply is empty when opened on an R file.

This is the content of my ~/.ctags file:
--langdef=Splus
--langmap=Splus:.s.S.R.r.q
--regex-Splus=/^[ \t]+"?([.A-Za-z][.A-Za-z0-9_]*)"?[\t]*<-[\t]*function/\1/
--regex-Splus=/^"?([.A-Za-z][.A-Za-z0-9_]*)"?[ \t]*<-/\1/

What do I have to do, to make Taglist recognize my customizations?

Kind regards and thank you for any help you can provide.
And of course: A prosperous and happy new year!
