Here's a QD bit of code I wrote up a while back. Dunno if it'll be of
any use in setting up your tickmarks.
# x, n same meaning as in pretty()
# update: check for x neg or zero
# ... is for other args to pretty()
prettylog- function(x,n=10,base=10,...) {

If you do write your own, the hardest part will be picking the nice tick
marks. They should be approximately evenly spaced, but at nice round values
of the original variable: that's hard to do in general. R has the pretty()
function for the linear scale, and doesn't do too badly on log
