David Bailey and Jens-Peer Kuska both gave me good answers. Thanks to them!

  My question was prompted out of a wish to save myself from reinventing the 
wheel. The "LinTicks" function produces nice ticks for plots, and I've dug 
into it before to make my own definitions, but I wanted to avoid that in this 
case. The answers given allow me to manipulate the values returned by 
LinTicks. I'll summarize them below.
