CRAN local repository

How to set up a package repository

Guide: http://cran.r-project.org/doc/manuals/R-admin.html#Setting-up-a-package-repository

To create CRAN repository

Dry run

rsync -avn cran.r-project.org::CRAN > crandryrun.txt

To mirror only partial repository, it is necessary to create directories before running rsync command.

mkdir /media/WD640/CRAN
mkdir /media/WD640/CRAN/bin
mkdir /media/WD640/CRAN/bin/windows
mkdir /media/WD640/CRAN/bin/windows/contrib
mkdir /media/WD640/CRAN/bin/windows/contrib/2.15
rsync -rtlzv --delete cran.r-project.org::CRAN/bin/windows/contrib/2.15/ /media/WD640/CRAN/bin/windows/contrib/2.15
(one line with space before /media)
rsync -rtlzv --delete cran.r-project.org::CRAN/src/ /media/WD640/CRAN/src/

And optionally

library(tools)
write_PACKAGES("/var/www/CRAN/bin/windows/contrib/2.15", type="win.binary") 

We can use du -h to check the folder size.

To create Bioconductor repository

Dry run

rsync -avn bioconductor.org::2.11 > biocdryrun.txt

Then creates directories before running rsync.

The software part:

mkdir /media/WD640/Bioc/packages/2.11/bioc
mkdir /media/WD640/Bioc/packages/2.11/bioc/bin
mkdir /media/WD640/Bioc/packages/2.11/bioc/bin/windows
rsync -zrtlv  --delete bioconductor.org::2.11/bioc/bin/windows/ /media/WD640/Bioc/packages/2.11/bioc/bin/windows

and annotation part:

mkdir /media/WD640/Bioc/packages/2.11/data
mkdir /media/WD640/Bioc/packages/2.11/data/annotation
mkdir /media/WD640/Bioc/packages/2.11/data/annotation/bin
mkdir /media/WD640/Bioc/packages/2.11/data/annotation/bin/windows
rsync -zrtlv --delete bioconductor.org::2.11/data/annotation/bin/windows/ /media/WD640/Bioc/packages/2.11/data/annotation/bin/windows

To test local repository

To test CRAN

r <- getOption("repos"); r["CRAN"] <- "http://arraytools.no-ip.org/CRAN"
options(repos=r)
install.packages("pamr")

To test Bioconductor

options("BioC_mirror" = "http://arraytools.no-ip.org/Bioc")
source("http://bioconductor.org/biocLite.R")
# This source biocLite.R line can be placed either before or after the previous 2 lines
biocLite("aCGH")

If there is a connection problem, check folder attributes.

chmod -R 755 ~/CRAN/bin

Note that if a binary package was created for R 2.15.1, then it can be installed under R 2.15.1 but not R 2.15.2. The R console will show package xxx is not available (for R version 2.15.2).

For binary installs, the function also checks for the availability of a source package on the same repository, and reports if the source package has a later version, or is available but no binary version is. So for example, if the mirror does not have contents under src directory, we need to run the following line in order to successfully run install.packages() function.

options(install.packages.check.source = "no")

Hidden tool: rsync in Rtools

c:\Rtools\bin>rsync -avz "/cygdrive/c/users/limingc/Downloads/a.exe" "/cygdrive/c/users/limingc/Documents/"
sending incremental file list
a.exe

sent 323142 bytes  received 31 bytes  646346.00 bytes/sec
total size is 1198416  speedup is 3.71

c:\Rtools\bin>

And rsync works best when we need to sync folder.

c:\Rtools\bin>rsync -avz "/cygdrive/c/users/limingc/Downloads/binary" "/cygdrive/c/users/limingc/Documents/"

Unforunately, if the destination is a network drive, I could get a permission denied (13) error. See also http://superuser.com/questions/69620/rsync-file-permissions-on-windows
