Comment(by mvngu):
As of Sage 4.3.2.alpha1, ticket #6532 upgrades R to version 2.10.1. From
what I gather, after installing an R package, one needs to restart Sage:
{{{
[mv...@mod sage-4.3.2.alpha1]$ ./sage

It didn't say to use the command `r.restart()`. What about issuing
`reset()` after installing an R package? It works for me:
{{{
sage: r.install_packages("igraph")
<downloading-compiling-messages>
* DONE (igraph)
The downloaded packages are in
‘/tmp/RtmpllHMEs/downloaded_packages’

>
Please restart Sage in order to use 'igraph'.
sage: reset()
sage: r.library("igraph")
}}}
Perhaps you want the command `r.restart()` to achieve the same effect as
`exit` and `reset()`? That is, one could install an R package with
`r.install_packages("pkg-name")`, run `r.reset()`, and then load the newly
installed package with `r.library("pkg-name")`? As a side note, one could
not install R packages with a binary Sage distribution.
