By "too much control" do you mean that axis requires too many inputs?
You can use axTicks to get the positions of the tick marks that would have
been drawn and create labels based on those positions. E.g.,
> myAxis <- function (side) {
at <- axTicks(side = side)
lab <- ifelse(abs(at)>=1e6, paste(at/1e6, "M"), paste0(at/1e3, "k")) #
alter to suit your tastes
axis(side = side, at = at, lab = lab)
}
> plot(c(1,1200), c(1,1e6), axes=FALSE)
> myAxis(side=1) # "0k", "0.2k", ..., "1.2k" on x axis
> myAxis(side=2) # "0k", ..., "800k", "1M" on y axis
