I think this is what you need https://launchpad.net/ubuntu/vivid/+package/r-cran-plyr

Choose the version you need from the Published versions section, then on the right you will see Downloadable files.

They are debs so no compiling required.

  • The OP asked about 14.04, not 15.04. These are deb package with compiled code so you can't generally just pick them randomly. This is bad advice, consider removing the answer. – Dirk Eddelbuettel May 08 '15 at 11:30
  • Well you are now both rude and clueless. You are mixing the R package system with the one from the distro, and you are using the latter the wrong way. – Dirk Eddelbuettel May 08 '15 at 11:42
  • Oh, AND they will have been created by the wrong R version. – Dirk Eddelbuettel May 08 '15 at 11:46
  • First, update R: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 sudo sh -c "echo 'deb http://streaming.stat.iastate.edu/CRAN/bin/linux/ubuntu quantal/' >> /etc/apt/sources.list" sudo apt-get update sudo apt-get install r-base r-base-dev Then install codetools package from R: install.packages("codetools") After this, the installation of plyr go smoothly. – Santhosh Adiga U May 08 '15 at 11:48
  • Still wrong. While the CRAN repos are a good idea, they *assume that your R version is current* whereas OP specifically stated that this version is 3.0.2. You provide him with an upgrade path (which is helpful) but it is not what he asked for. Anyway, the question is a FAQ and I pointed to a better (collected) answer already on SO. – Dirk Eddelbuettel May 08 '15 at 12:23
