Hi.
Use of tilde in filenames passed to graphics drivers crashes R on Mac
(2.7.1.45970/i386/9.4.0/MacBookPro3,1/2/4). This is true in the GUI
as well as on the command line. For example...
png("~/myplot.png")
plot(cos)
dev.off()
...causes a crash. tiff() has the same problem. jpeg() does not
crash, but the display of the image seems unreliable.
In Windows, all three issue a warning, though png() warns on
initialization, while tiff() warns on closure.
In both Windows and Mac, setwd("~/") has the expected effect,
suggesting that tilde expansion is supportable in principle.
Apologies if this is a known problem.
