Hi folks,
I'm having a bit of trouble getting plots or histograms using the r
interface in sage. I'm using the 3.0.2 ubuntu binaries. I noticed
that trac # 2978 http://sagetrac.org/sage_trac/ticket/2978 shows that
people are aware of this issue already (R not being built with png
support). I was wondering if there is a simple way to manually
rebuild R with png support. I didn't see a configure or makefile in
the R subdirectory.
JPEG export also fails, but it seems silently. The follow code :
a=[random() for i in range(500)]
r.jpeg('histogram.jpeg',width=640,height=480)
r.hist(a,main="test",col="lightblue",prob=True, xlab="val of
random()")
r.lines(r.density(a,bw=0.05),col="black")
r.rug(a)
r.dev_off()
has an output of [1] 0.05, but that is it.
Thanks,
Thomas
