Well, no one answered this back in August, and now I have the same
problem with another figure.
Again, is there some way to position several lines of text within
a plot written at different cex sizes so that the relative spacing of
the lines remains fixed when the plot is resized or written to
a device?
That is, I'd like to have such caption text treated as a fixed block
which, under rescaling would expand contract uniformly.

This question has probably been asked & answered before, but I can't
find it: How to print a
multiline figure caption in a plot, where different lines have different
fonts and font sizes,
and so that the lines of text are spaced in a reasonable way.
Here's a simple example, where I have to keep tweaking the y coordinate
and the
cex combos, while I also manually adjust the aspect ratio of the plot.
But, once I get it looking
OK on the screen, when I print to a PDF device, the lines of text move
around.
op <- par(mar=c(4,4,1,1)+.01) # tight bounding box
plot(1:79, type="n",
xlab="Year", ylab="", cex.lab=1.5,
xlim=c(1500, 2000))
text(1610, 75, "Specimen of a\nChart of Biography", cex=2.5, font=4)
text(1610, 69, "of Milestones Authors", cex=1.5, font=4)
par(op)
In my real application, I would also add other lines of text in a
smaller font size.
