Unable to install R package in Ubuntu 11.04 [closed]
The install.packages method
You need to install the ubuntu package libxml2-dev So in a shell prompt type:
sudo apt-get updatesudo apt-get install libxml2-devYou will need special sudo powers for this.
Ubuntu package method
As Richie and Dirk mentioned, you can also use:
sudo apt-get install r-cran-xmlIf you go down this path, I would recommend that you check out the R ubuntu sources page which will ensure you have a current version of R and the associated R packages. This could be important if you are using the LTS version of ubuntu.
The answer by Colin is correct in a narrow sense, but at the same time wrong as you can just say
sudo apt-get install r-cran-xmlas XML is one of the CRAN packages available in Ubuntu. Do apt-cache search r-cran-* do see the others.
