The DC command can sweep resistors, too.  Unlike Spice, it isn't 
limited to sources.

The sweep command can do a log sweep.  Just put the word "log" 
ahead of the number of points....

gnucap>build
V1 1 0 1

>>>op
>>>go


I showed a voltage source, and op command here because you can 
easily see the result.  It works for resistors too, and you can 
use any commands, like AC.
