Hi folks,

......
installing to /usr/local/lib/R/site-library/mapproj/libs
** R

** preparing package for lazy loading
** help
*** installing help indices
** building package indices ...
** testing if installed package can be loaded

* DONE (mapproj)

The downloaded packages are in
    ‘/tmp/Rtmp3CKVAs/downloaded_packages’
Warning messages:
1: In install.packages("TeachingDemos", dependencies = TRUE) :
  installation of package 'tkrplot' had non-zero exit status
2: In install.packages("TeachingDemos", dependencies = TRUE) :
  installation of package 'rgl' had non-zero exit status


What do the warnings indicate?  Was the package installed correctly?  TIA
