The problem comes from trying to create a .png of a figure in Windows
XP, with R2.1.0. On the screen it looks OK, but in the .png the text
for the x label is smaller than for the y label. The problem seems to
be created by using axes=F in plot(). Here's some code to demonstrate
the problem:
XX=1:5; YY=1:5
png("thing.png")
par(mfrow=c(2,1))
plot(XX, YY, axes=F, xlab="X label", ylab="Y label")
plot(XX, YY, xlab="X label", ylab="Y label")
dev.off()
I get a similar problem with bmp() and jpeg(), but not postscript() or
pdf(). If I draw the figure in the window in R and then save it as a
.png from the menu, the png looks fine.
Everything works fine in R1.5.1 (I know, I know!) on Debian Linux, which
is why I'm reporting this as a Windows problem.
I see the problem in the first figure, and it's still there in a recent r-devel build. My test was also on Windows. Since png() uses the Windows graphics driver, it does look like an R bug in the Windows graphics driver, but I'd like to hear from someone on a different platform... Duncan Murdoch
