[R] How to suppress factor labels
I am using ggplot2 to make a boxplot that overlays a scatterplot: pp = qplot(time, error, data=times, size=I(1), geom=jitter, main=title, ylab=Error (min), xlab=Time before ON (min), alpha=I(1/10), color=times$runway, ylim=c(-30,40)) pp2 = pp + with(times, facet_wrap(~ runway, ncol=2)) print(pp2 + geom_boxplot(alpha=.5, color=blue, outlier.colour=green, outlier.size=1)) The x variable is a factor for every minute from 0:60. My problem is that ggplot2 labels every factor value on the x axis, and they overlap. How can I make ggplot2 label only, say every 5th factor value on the x axis?

Re: [R] How to suppress factor labels
I think the issue is that the x axis is a factor. How would ggplot2 know which ones to drop? So it labels them all. If I do the following, the labels get better: pp = qplot(time, error, data=times, size=I(1), geom=jitter, main=title, ylab=Error (min), xlab=Time before ON (min), alpha=I(1/10), ylim=c(-30,40)) pp2 = pp + with(times, facet_wrap(~ runway, ncol=2)) + scale_x_discrete( breaks = c(0, 5, 10, 15,20,25,30,35,40,45,50,55,60), labels=c(0, 5, 10, 15,20,25,30,35,40,45,50,55,60)) print(pp2 + geom_boxplot(alpha=.5, color=blue, outlier.colour=green, outlier.size=1)) But this ruins the boxplot--I get one box instead of a box at every minute.

In the data you sent, time is numeric, not a factor. This works for me: qplot(factor(time), error, data=times, size=I(1), geom=boxplot) + facet_wrap(~ runway, ncol=2) + scale_x_discrete(breaks = seq(from=0, to=60, by=10)) Best, Ista How would ggplot2 know which ones to drop?
