How do I change the font size in the facet labels along the edges of the
plot?
For example (from the ggplot help file):
p<-ggplot(tips, sex ~ smoker, aesthetics=list(x=tip/total_bill))
gghistogram(p)
In this plot, the facet labels are "smoker: No", "smoker: Yes", "sex:
Female", "sex: Male". What command can I use to reduce the font size of
these labels?
In lattice terminology, cex is used to scale these strip labels. But I
couldn't find the equivalent in ggplot.
The reason I'm asking is I have a 9x7 array of plots which I've been
plotting with lattice. I wanted to use ggplot because I like having the
labels on the edge of the plots, but the label font size is too large
and exceeding the size of the label box.
Thanks in advance...
