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.
A completely different device, as is the standard Unix one (and that does
support tilde-expansion).
In both Windows and Mac, setwd("~/") has the expected effect,
suggesting that tilde expansion is supportable in principle.
In principle, yes. By the particular utility software used, not
necessarily (which is why png and tiff behave differently on Windows).
Apologies if this is a known problem.
