Multi-panel titles in R
I have an ultra short question about R
My aim is to assign a common title to a multi-panel plot generated using par, e.g.
par(mfrow=c(1,2))
plot(rnorm(1000))
plot(rnorm(1000))
So, something like "mai开发者_StackOverflow中文版n" for the plot function, but extended to both plots. Is there a canonical way to do this?
Thanks for any answer :-)
Use mtext
with option outer
:
set.seed(42)
oldpar <- par(mfrow=c(1,2), mar=c(3,3,1,1), oma=c(0,0,3,1)) ## oma creates space
plot(cumsum(rnorm(100)), type='l', main="Plot A")
plot(cumsum(rnorm(100)), type='l', main="Plot B")
mtext("Now isn't this random", side=3, line=1, outer=TRUE, cex=2, font=2)
par(oldpar)
