Hi Simon,
dpi=100 works great. Thanks!

Hank,
R 2.7.0 (unlike previous versions) allows non-square pixels and
determines the pixel aspect ratio from the physical dimensions of the
screen (unless specified directly). In your case I suspect that the
reported physical dimensions are that of the non-rotated screen
whereas the pixel dimensions are rotated - that will result in a bogus
dpi.
Try setting dpi=100 (or the exact x and y resolutions of your screen
if you know it). That should fix the problem (you can use
quartz.options to make the change permanent).
Unfortunately CGDisplayRotation is only available in Mac OS X 10.5 so
we cannot require it to determine the rotation. I have added some
heuristics to match the orientation of the physical and pixel
dimensions. It may throw off some unusual geometry screens but it
should work in your case (sort of the most usual unusual case ;)), so
please try tonight's R-devel or R-patched.
Thanks,
Simon

Hi Folks,
I am using R version 2.7.0 (2008-04-22). The problem I describe is
new since 2.6.2.
I find that
x11(width=7, height=7)
gives me a square device but
quartz(,7,7)
or
plot(1:10)
results in a quartz device that does not appear square on my machine
- the aspect is distorted compared to the X11 device. It looks
stretched too tall and a tiny bit too narrow.
I am not sure if any of this is relevant:
I am on a Mac (10.5.3) and have two Dell monitors on their sides so
I have two tall side by side screens. The resolutions are both 1024
x 1280, and they are rotated 90 and 270 deg.
My .RProfile includes
grDevices::ps.options(horizontal = FALSE)
.First <- function() {cat(paste(date()),"\nRecepcion al R asombroso,
dude!\n\n")
#library(CarbonEL)
# Sys.setenv("DISPLAY"=":0")
options(device="quartz")
}
Thanks for any thoughts.
Hank
