[R] Updating Package Fails: Help on How to Fix Needed

[Rich Shepard]

   Trying to update package pbkrtest failed because of a missing object in
another namespace. Not having experienced this issue before now I don't know
what to do to fix the problem. Here's the story:

* installing *source* package ‘pbkrtest’ ...
** package ‘pbkrtest’ successfully unpacked and MD5 sums checked
** R
** data
** inst
** preparing package for lazy loading
Warning: replacing previous import by ‘stats::sigma’ when loading ‘pbkrtest’
Error : object ‘sigma’ is not exported by 'namespace:stats'
ERROR: lazy loading failed for package ‘pbkrtest’
* removing ‘/usr/lib/R/library/pbkrtest’
* restoring previous ‘/usr/lib/R/library/pbkrtest’

The downloaded source packages are in
 	‘/tmp/RtmppHtiuJ/downloaded_packages’
Updating HTML index of packages in '.Library'
Making 'packages.html' ... done
Warning message:
In install.packages(update[instlib == l, "Package"], l, contriburl =
contriburl,  :
   installation of package ‘pbkrtest’ had non-zero exit status

   Advice needed.
