[R-sig-Debian] clean wheezy, R intrigue, squeeze-cran3 requires liblzma2?

[Johannes Ranke]

Hi,

The R 3 packages for wheezy are currently being built for i386 and amd64. If 
all goes well, they will be available within the next two days.

As for R on Debian wheezy, I just checked demo(plotmath) on the default R 
2.15.1 on wheezy, and it produced all the nice plotting symbols I would expect 
in good quality. I realize this does not help you, I just want to make clear 
that wheezy is not the problem here.

I will check the wheezy backport for proper functioning of plotmath.

Kind regards,

Johannes
