The now default Cairo results in much prettier graphs, but dense graphs such
as plot(rnorm(1e4)) take considerably longer to plot than using
X11(type="Xlib"). This has already been mentioned, but I was wondering if we
users could expect Cairo speed increases in the near future?

Thanks, running r44621 works well (on my FC5 box) and I can make various plots
(I just did some limited testing).
When I run the 'TestChars()' example in 'points' I get many warnings of the
form:
1: In plot.xy(xy.coords(x, y), type = type, ...) :
pch value '128' is invalid in this locale
2:
Revision r44621 supports (in a limited way) cairo 1.0 and hence I believe

quite well there.
Two people have reported that the svg(), cairo-pdf() and cairo-ps()
devices produce blank (but not empty) files. I was able to c

Offering an API is something I have considered for the TODO for 2.8.0.
However, we are

That call is from Cairo 1.2, so looks like our test FC5 box had a later
version of the cairo libraries than the one pkg-config reported.
You should be able to build with --without-cairo until such a time as we
can add a suitable configure test.
Thank you for the report.

(Apologies, I meant to 'Reply to all' the first time but forgot).
I built r44608 of R-devel with (I think) cairo support. At least,
that's what the configure script told me. In addition,
'capabilities("cairo")' is TRUE. Calling X11(type = "Cairo") gives me
the error:
Error in X11() : X11 modu
R-devel has new versions of the X11(), png() and jpeg() devices on
Unix-alikes. The intention is that these are used identically to the
previous versions (which remain available) but will produce higher-quality
output with more features.
