Install R from source
On my debian system in Pogoplug (armv5), I can compile R. If I don't need x11, I just need to install 2 required packages.
- install gfortran: apt-get install gfortran
- install readline library: apt-get install libreadline5-dev
Note: if I need x11, I should install
- libx11 and libx11-devel, libXt, libXt-devel (for fedora)
- xorg-dev (for debian)
I also run apt-get install readline-common. I don't know if this is necessary. Since I don't need x11, I use the option in configure command. After running
./configure --with-x=no --enable-R-shlib
I got
R is now configured for armv5tel-unknown-linux-gnueabi Source directory: . Installation directory: /usr/local C compiler: gcc -std=gnu99 -g -O2 Fortran 77 compiler: gfortran -g -O2 C++ compiler: g++ -g -O2 Fortran 90/95 compiler: gfortran -g -O2 Obj-C compiler: Interfaces supported: External libraries: readline Additional capabilities: NLS Options enabled: shared R library, shared BLAS, R profiling Recommended packages: yes configure: WARNING: you cannot build info or HTML versions of the R manuals configure: WARNING: you cannot build PDF versions of the R manuals configure: WARNING: you cannot build PDF versions of vignettes and help pages configure: WARNING: I could not determine a browser configure: WARNING: I could not determine a PDF viewer
However, make gave errors for recommanded packages like KernSmooth, MASS, boot, class, cluster, codetools, foreign, lattice, mgcv, nlme, nnet, rpart, spatial, and survival. The error stems from gcc: SHLIB_LIBADD: No such file or directory. Note that I can get this error message even I try install.packages("MASS", type="source").

Creating local repository for CRAN and Bioconductor
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
Before creating a local repository please give a dry run first. You don't want to be surprised how long will it take to mirror a directory.
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 (aka bioc directory) installation:
mkdir ~/Bioc/packages/2.11/bioc mkdir ~/Bioc/packages/2.11/bioc/bin mkdir ~/Bioc/packages/2.11/bioc/bin/windows mkdir ~/Bioc/packages/2.11/bioc/src rsync -zrtlv --delete bioconductor.org::2.11/bioc/bin/windows/ ~/Bioc/packages/2.11/bioc/bin/windows rsync -zrtlv --delete bioconductor.org::2.11/bioc/src/ ~/Bioc/packages/2.11/bioc/src
and annotation (aka data directory) part:
mkdir ~/Bioc/packages/2.11/data mkdir ~/Bioc/packages/2.11/data/annotation mkdir ~/Bioc/packages/2.11/data/annotation/bin mkdir ~/Bioc/packages/2.11/data/annotation/bin/windows mkdir ~/Bioc/packages/2.11/data/annotation/src rsync -zrtlv --delete bioconductor.org::2.11/data/annotation/bin/windows/ ~/Bioc/packages/2.11/data/annotation/bin/windows rsync -zrtlv --delete bioconductor.org::2.11/data/annotation/src/ ~/Bioc/packages/2.11/data/annotation/src
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")
- If we only mirror the essential directories, we can run biocLite() successfully. However, the R console will give some warning
> biocLite("aCGH")
BioC_mirror: http://arraytools.no-ip.org/Bioc
Using Bioconductor version 2.11 (BiocInstaller 1.8.3), R version 2.15.
