[R] changing the position of the y label (ylab)

[Stephen Tucker]

If by 'position' you mean the distance from the axes, I think 'mgp' is the
argument you are looking for (see ?par)-

You can set this in par(), plot() [which will affect both x and y labels], or
title():

par(mar=rep(6,4))
plot(NA,NA,xlim=0:1,ylim=0:1,xlab="X",ylab="")
title(ylab="Y2",mgp=c(4,1,0))

if you want to change 'position' parallel to the axis, then you probably have
to do
plot(...,xlab="",ylab="")

and set labels using mtext(); playing around with the 'adj' argument.

Btw, you can use '\n' to denote new line:
title(ylab="Onset/Withdrawl\nDate",mgp=c(4,1,0))
