I use several different versions of R, including RGui on Windows and
rstudio on Linux.? In all cases, I use graphical commands, such as
image().?
image() displays rectangles, but I want to be able to guarantee that the
heights of those rectangles will always equal the widths.? Typically, the
rectangles come out with notable asymmetries.
Thus, if I need to draw a perfect circle with square pixels, I usually get
a squashed ellipse with oblong pixels.
I have experimented with other commands, and I don't need to continue to
use image() if some other command would be more suitable.
Thanks.
