Hi Mike, You can use the ?axis function to add custom axes in. To prevent overwriting, you will want to suppress the default y axis in your call to plot. You can find details on the arguments and parameters in ?par (I recommend pulling it up in a way that you can search because the par documentation is very long though very useful).
Here is an example: ## something like what you might have plot(1:25, 1:25, ylim = c(5, 25)) ## plot suppressing the axis plot(1:25, 1:25, ylim = c(5, 25), yaxt = "n") ## add axis with your own breaks/labels axis(side = 2, at = 5:25) Cheers, Josh On Thu, Mar 10, 2011 at 10:08 AM, Mike Gibson <megalop...@hotmail.com> wrote: > > I want to increase the number of labels on my y-axis.
