[R] Where is package gridBase?

[Jonathan Dushoff]

Trying to follow the instructions on the page
http://tolstoy.newcastle.edu.au/R/help/05/12/17153.html (to make a
figure with an inset), I typed

> install.packages("gridBase", repos="http://cran.r-project.org")

and was rejected.

 	no package 'gridBase' at the repositories in: download.packages(pkgs,
 	destdir = tmpd, available = available,

I went to the FAQ at
http://cran.r-project.org/doc/FAQ/R-FAQ.html#Add_002don-packages-from-CRAN,
and was informed that gridBase was an add-on package available from
CRAN.

I also tried installing other packages using exactly the same command.

> install.packages("TeachingDemos", repos="http://cran.r-project.org")

These packages were apparently found:
 	trying URL
 	'http://cran.r-project.org/src/contrib/TeachingDemos_1.2.tar.gz'
 	Content type 'application/x-tar' length 66472 bytes
 	opened URL

 	(and so on)

I would appreciate any insight that anyone might have.
