R help - Jun 2008 - controlling location of labels in axis()

Here's a naive question about axis()

How do you control the location of the labels with the axis() command?

In the following example:

foo <- data.frame(plot.x=seq(1:3), plot.y=seq(4:6))
plot(foo$plot.x, foo$plot.y, type='n', axes=FALSE)
points(foo$plot.x, foo$plot.y)
axis(1, at=foo$plot.x, labels=foo$plot.x)

I'd like to be able the control the y location of the labels (i.e. move up
or down in the graph).

Thanks,
Andrew

Hi Andrew,

Perhaps this example would help. You can add in spaces to the mtext text
to move the text sideways.

par(mai=c(0.5,0.5,0.5,0.5),oma=c(2,2,2,2))	#mai units are INCHES, oma
units are LINES
plot(runif(50),xlab="xlab",ylab="ylab",bty="l")
#n.b. these labels don't
appear
mtext("First inner x axis label",side=1)
mtext("First inner y axis label",side=2)
mtext("Second inner x axis label",side=3)
mtext("Second inner y axis label",side=4)
mtext("First outer x axis label",side=1,outer=TRUE)
mtext("First outer y axis label",side=2,outer=TRUE)
mtext("Second outer x axis label",side=3,outer=TRUE)
mtext("Second outer y axis label",side=4,outer=TRUE)

Cheers,
Toby Marthews
