$ sudo rstudio-server start
If that doesn't get it going, try running the installation verification tool:
$ sudo rstudio-server verify-installation

Installing RStudio
Installing RStudio is usually a straightforward process.
First, RStudio requires a working, relatively modern R installation. If that is not already present, then one should consult
http://cran.r-project.org/ to learn how to install R for the given operating system. For Windows and Mac OS X, one can simply download a self-installing binary; for Linux, installation varies. For the Debian distribution (including Ubuntu), the R system can be installed using the regular package-management tools. Of course, as R is open source, one can also compile and install it using the source code.
The RStudio package is available for download from
http://www.rstudio.org/download/ There is a choice between a Desktop version and a Server version. The Desktop version is appropriate for single-user use. The files come in a common format for binary installation (e.g., exe, dmg, deb, or rpm). One downloads the file and installs it as any other program.
For those searching out the latest features, follow the link on
http://www.rstudio.org/download/daily to get the binaries for the most recent (but not necessarily stable) build.
Installing a server version requires more work and care. Some directions are given at
http://rstudio.org/docs/One can also install RStudio from its source code. A link for the source “tarball” for the current stable version appears on the appropriate download page. For the adventurous, the latest development build files are available from
https://github.com/rstudio/rstudio. Installation details are in the INSTALL file accompanying the source code. The same source is used to compile both the Desktop and Server version.
As RStudio depends on some of the latest features of many moving parts, such as GWT, there can be issues with compiling from the source. The support forums (http://support.rstudio.org/) are an excellent place to find specific answers to any issues.
