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.

Please check your fonts (Applications -> Font Book) and make sure Arial and Helvetica are not disabled or corrupted (those are the defaults - if you changed your font settings in R check the corresponding fonts).

Cheers,

Help?
