Multi-line y label in plot

Question

Is there a way to create multi-line labels for the y axis in an R plot?

I have tried adding a \n where the newline should be, but then the first line of the label gets clipped:

l <- 10
plot(0:l, (0:l), type='l',
     yaxt='n',
     xlab='Index',
     ylab='Cumulative sum\nof the sorted weights')

This happens both with the tikzDevice and inside RStudio. Also, I tried some of the par() options with no luck. How to do it properly?

(The oversized uper margin bothers me, too...)

Solution 1

You need to set the margins using mar or mgp:

l <- 10
op <- par(mar=c(5, 6, 4, 2) + 0.1)
plot(0:l, (0:l), type='l',
     yaxt='n',
     xlab='Index',
     ylab='Cumulative sum\nof the sorted weights')
par(op)

Solution 2

Like @smillig suggested, you do it with par, changing the mar or mgp parameters.

But you have to call par before you call plot.
