Here's a Q&D 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,...) {
x<-unlist(x)
if (min(x

Dear R users,
while I enjoy the built-in log argument to the plot() function, I wished it

sqrt(), logit, etc...
for example, instead of
plot(x=exp(rnorm(10)), y=(1:10)^4, log = "xy"), sth. along the li
