I am trying to install rscproxy and rcom packages on windows. I tried the following methods:

Method 1:

Opening R as administrator and using this command

>install.packages(c("rscproxy","rcom"),repos="http://rcom.univie.ac.at/download",lib=.Library)

But getting error as unable to access the url.

Method 2:

Downloaded the zip of the packages from cran and using this command

>install.packages('D:\\rscproxy_2.0-5.zip', lib='C:\\Program Files\\R\\R-3.1.1\\library',repos = NULL)
package ‘rscproxy’ successfully unpacked and MD5 sums checked
> install.packages('D:\\rcom_2.2-5.zip', lib='C:\\Program Files\\R\\R-3.1.1\\library',repos = NULL)
package ‘rcom’ successfully unpacked and MD5 sums checked

But then:

> library(rcom)
Error: package ‘rcom’ was built before R 3.0.0: please re-install it

I also referred these How do I install an R package from source? and Manually Downloading and Installing Packages in R but all in vain.

Please help me with any fix for this.

P.S : I am using R 3.1.1 on 32-bit Windows 7

    From their download.html page:" CRAN is not hosting some of the components of our software any more. RAndFriends depended on these componetes to be available on CRAN. Therefore, to use our tools, R has to be installed manually. Our Wiki has < a href="http://homepage.univie.ac.at/erich.neuwirth/php/rcomwiki/doku.php?id=wiki:how_to_install>" So did you follow the instuctions on that page to create an "upgraded" version of R? – IRTFM Jan 08 '15 at 07:40

  • @BondedDust Yes I already followed their instruction(see method 1 above) but getting error. – Leo Jan 08 '15 at 09:03
