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]) (f_angle <- atan(myasp)*180/pi) (g_angle <- atan(2*myasp)*180/pi) -- Levi Waldron post-doctoral fellow Jurisica Lab, Ontario Cancer Institute Division of Signaling Biology TMDT 9-304D 101 College Street Toronto, Ontario M5G 1L7 (416)581-7453 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
