R help - Mar 2006 - [Q] How to make a multi-line title with expression()

Dear R-lister

Could anyone know how to make a multi-line title for a plot with
expression()?
In my plot, the title should be writeen in two lines (because it is two long
for one line) and it should use a mathematical expression. I tried to use
"\n", but "\n" is ignored in expression() call:
hist(diffChangeRequestHintsBeforeAnswering[,4], br = 50, xlab = "Skill
Change in Standard Deviation", main = expression(paste("(a)
H&S", F[A],
"\nRequest hint(s)/subtask(s) before first attempt")))

Thanks in advance.

Try RSiteSearch("multi-line expression").

Young-Jin,

The expression

tit1 <- "Max. Daily Wind Speed \nSydney Airport"

hist(ws,xlab='Wind Speed',ylab='Freq.",main=tit1)

works fine in my case. Try using your title between
one set of quotes. 

Hope it helps,

Augusto
