How can I install packages that are in archive, in Windows ?
http://cran.r-project.org/src/contrib/Archive/
When I try to install the tar.gz downloaded from the archive I get the following error:
Error in gzfile(file, "r") : cannot open the connection In addition: Warning messages: 1: In unzip(zipname, exdir = dest) : error 1 in extracting from zip file 2: In gzfile(file, "r") : cannot open compressed file 'grasp_2.5-7.tar.gz/DESCRIPTION', probable reason 'No such file or directory'
You can try the function install_version in devtools. Let us suppose you want to install version 0.8 of ggplot2, you can call it as install_version('ggplot2', '0.8'). If you are on Windows, you can follow the instructions here to build packages from source.
You can download the sources (tar.gz files) and install them using:
R CMD INSTALL packagename.tar.gz
I had the same problem installing graph package from archive. The package is required for another package (bnclasify).
chooseBioCmirror() #select a different mirror than CRAN. This mirror may be #because is the one that has bnclasify in it (check this statement)
setRepositories() #In here you can select as many as you want to search for the #package you need
ap <- available.packages() #list of all available packages
"graph" %in% rownames(ap) #search the package you need by name (return TRUE or #FALSE).
install.packages("graph", dependencies=TRUE) #if the last statement TRUE then #install the package like normally
