This is a general question, not specific to OS X.
Colleagues
Often, one or more values on an axis will be omitted, presumably in order to
prevent overlap. However, there are situations where I would like to override
that omission. Sample code:
pdf("labels.pdf", width=3, height=3)
plot(0:100, 0:100)
graphics.off()
Here, 100 is omitted from the x-axis and 20, 60, and 100 from the y-axis.
Is there is automated way to detect which values will be omitted (i.e., without
seeing the graphic)?
If so, I see two options:
1. change the font size
2. force the entry, e.g., axis(1, 100, at=100)

I don't think you can tell in advance since the details of the plot are
computed when you open the plot window and they change when you plot into the
window. In principal you could estimate the size requirements for the axis
labels if you know the plot window size and the character size. What gets
plotted is also device dependent. For example if you open a window using x11(3,
3) (I'm on windows so I haven't tried this on OS X) and produce the
plot, the last x-axis is missing just as in the pdf file. But if you drag the
window to make it larger, the label will appear when the device driver redraws
the plot.
There is also a third option in addition to your two to getting all of the
labels:
plot(0:100, 0:100, xaxp=c(0, 100, 4))
will plot at 0, 25, 50, 75, 100 which leaves room for the last label.

Hi Dennis, Perhaps you were looking for "staxlab" in the plotrix package.
