R
How to set up a package repository
http://cran.r-project.org/doc/manuals/R-admin.html#Setting-up-a-package-repository
To test CRAN,
r <- getOption("repos"); r["CRAN"] <- "http://arraytools.no-ip.org/CRAN"
options(repos=r)
install.packages("pamr")
For 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).
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/"
