There are two clues:

 i)  R always installs all files for package 'foo' in a top-level directory
     'foo' below the entry of the library paths select -- if not set, it uses
     the default which is the first element returned by .libPaths()

     in your case:  'tkrplot' below  /usr/lib64/R/library/

 ii) For every package foo with to-be-compiled source code, R (on Linux)
     always creates a shared library libs/foo.so in the per-package directory
     tree. 

     in your case:  'tkrplot'

As an added bonus, can can always Google for the file itself. That would have
led you to tkrplot too.
