Maybe help.search(), or the search item at the R-project website? The
following packages (among others) include kriging in some form or other.
The spatial package in the VR bundle is installed by default. The sgeostat
package is interpreted. Both of fields and geoR are compiled - so there's
no lack of choice!

Comparison with recent Arc/Info is more difficult, the work being done
there by Konstantin Krivoruchko and others is impressive. Maybe try
several R packages and AI on the same real data to get a feel for how they
perform in relation to your needs? The resources on 
http://www.ai-geostats.org/ may also help.
