A supplementarily handy  but trivial  tip  for installing older version of packages from source   First  if you call  install packages   it always installs the latest package from repo  If you want to install the older version of packages  say for compatibility  you can call install packages  url to source   repo NULL  type  source    For example   install packages  http   cran r-project org src contrib Archive RNetLogo RNetLogo 0 9-6 tar gz   repo NULL  type  source     Without manually downloading packages to the local disk and switching to the command line or installing from local disk  I found it is very convenient and simplify the call  one-step     Plus  you can use this trick with devtools library s dev mode  in order to manage different versions of packages   Reference  doc devtools

If you have the file locally  then use install packages   and set the repos NULL     install packages path to file  repos   NULL  type  source     Where path to file would represent the full path and file name    On Windows it will look something like this   C   RJSONIO 0 2-3 tar gz   On UNIX it will look like this    home blah RJSONIO 0 2-3 tar gz

Download the source package  open Terminal app  navigate to the directory where you currently have the file  and then execute   R CMD INSTALL RJSONIO 0 2-3 tar gz   Do note that this will only succeed when either  a  the package does not need compilation or b  the needed system tools for compilation are present  See  https   cran r-project org bin macosx tools
