Comment(by kcrisman):
Okay, I have dug into this, and here are some preliminary thoughts.
We have a function r.png, which only works if capabilities('png') returns
TRUE. In the default build on Mac, we get
{{{
> capabilities()
jpeg png tiff tcltk X11 aqua http/ftp sockets
FALSE FALSE FALSE TRUE FALSE FALSE TRUE TRUE
libxml fifo cledit iconv NLS profmem cairo
TRUE TRUE TRUE TRUE TRUE FALSE FALSE
}}}
However, to build with X11 (which would enable png and friends) or with
aqua on Mac (which would enable the quartz graphics device), we need to
build with certain options. See [http://CRAN.R-project.org/bin/macosx
/RMacOSX-FAQ.html] and [http://cran.r-project.org/doc/manuals/R-admin.html
#Configuration-options] for some info.
On sagenb.org, however, we do have png and Cairo TRUE, though X11 FALSE.
The commands that give various errors on my computer in the description
instead give the actual data set (!) on sagenb, except the last one which
still returns NULL. However, the following DOES work (from the
documentation in interfaces/r.py):
{{{
r.png('temp.png')
x = r([1,2,3])
y = r([4,5,6])
r.plot(x,y)
r.dev_off()
}}}
So it seems that one can do this, but it's annoying. Similarly:
{{{
r.png('temp2.png')
r.plot('MPG.highway ~ Weight', data='Cars93')
r.dev_off()
}}}
works on sagenb. It's very nice, in fact!
So presumably if we enabled X11 on Mac (perhaps on a case-by-case basis
for each version of OSX as in the above websites) we would get this at
least, and perhaps also enabling aqua would solve this on Mac. To be
continued...
