That is true with screen output, although I ca
For posterity's sake, here is the solution I figured out. Putting the
following lines after the plot(f) command seems to set the angle correctly:
myasp <-
(par("fin")[2]-par("mai")[1]-par("mai")[3])/(par("fin")[1]-par("mai")[2]-par("mai")[4])

How can I look up the aspect ratio of a plot, so I can use that to correctly
adjust the angle of text which is supposed to be parallel to a line in the
plot?
The following example code works for a 1:1 aspect ratio, but puts the text
at the wrong angle if the plot region is short and wide or tall a
