On debian-based systems, the easiest way to install R is through a package manager manager, run under an administrator account. On Linux one usually needs to install R packages from source, and R package source often contains C, C++, or Fortran code requiring a compiler and -dev versions of various system libraries. It is therefore convenient to install the -dev version of R.
sudo apt-get install r-base r-base-devWhen installing source packages, it may be necessary to have access to the -dev version of various system libraries. Many of these are installed as dependencies of r-base-dev; other common examples include the xml and curl libraries
sudo apt-get install libxml2-dev
sudo apt-get install libcurl-devNote in particular the use specification of libraries (the lib prefix) and the use of the -dev version.
To install RStudio, visit the RStudio download page. Download the appropriate archive for your OS. On Ubuntu, install the .deb installer with
sudo dpkg -i rstudio-1.0.136-amd64.deb
