ggplot2: scale_y_continuous number of ticks

Question

I want to increase number of ticks on my Y axis and don't know how can I achieve this.

This answer (https://stackoverflow.com/a/11335933/1286528) is helpful - suggests to use scale_y_continuous(breaks = round(seq(min(dat$y), max(dat$y), by = 0.5),1)).

Problem is that I am using scale_y_continuous(limits = quantile(data, c(0.1, 0.9))) command already and don't know where to add additional command for number of ticks.

Answer 1

You can add a breaks = … right after your limits = … since it's a separate parameter to scale_y_continuous which is really just a call to continuous_scale. Do a ?continuous_scale at an R console prompt to see the help on it which will show you all the possible parameters.
