Hi:
I've been using R on my MacBook (OS X 10.6.3, 2 GHz Intel Core Duo) for a
couple of months now. I've noticed that whenever I plot a graph, the output
never shows indices for the axes. It shows tick marks on the side of the
graph, but no text. e.g.
> test = merge(seq(1:10), seq(1:20))
> plot(test)
shows the correct plot, with 4 tick marks up the side of the Y axis, 5 tick
marks down the X axis, but NO text or numbers anywhere.
As another example, a pairs() plot doesn't show any text along the diagonal
boxes, as it should.
That's normally a symptom of setting the margins too small to hold the
text, or (equivalently) the text too big to fit in the margins. Take a
look at par(), in particular see if you've changed the default values
$cex.axis
[1] 1
$mar
[1] 5.1 4.1 4.1 2.1
If you haven't changed those, then it looks like a font problem: R
thinks your default font is too big to fit. The default font is
determined by the par() setting
$font.axis
[1] 1
as well as defaults specific to your graphics device. I don't have my
Mac here, so I can't tell you what the default font is supposed to be on
your Mac.
