[R-SIG-Mac] Vignette package 'parallel'?

[Marius Hofert]

Hi,

I couldn't find the vignette for the package 'parallel' (Mac OS X 10.7.3; R
2.15.0). I then tried to (re)install the package (I know I comes with R
natively). I obtained:

,----
| > require(parallel)
| Loading required package: parallel
| > vignette(package="parallel")
| no vignettes found
| > install.packages("parallel", type="source")
| Installing package(s) into ‘/Library/Frameworks/R.framework/library’
| (as ‘lib’ is unspecified)
| Warning: unable to access index for repository http://cran.ch.r-project.org/src/contrib
| Warning: unable to access index for repository http://www.bioconductor.org/src/contrib
| Warning message:
| package ‘parallel’ is not available (for R version 2.15.0) 
| > 
`----

What's wrong? 

Cheers,

Marius

PS: Dirk Eddelbuettel sent me the vignette off-list, I just would like to know
how I could get it via 'vignette(package="parallel")'.
