R is a powerful language. From its ability to create complex statistical models with a few lines of code to its robust graphical capabilities and stunning data visualizations - R is a very handy language for any aspiring data scientist to learn. One of the main benefits of R is its robust community which provides support in the form of mailing lists, user-submitted documentation and various tutorials and helpful blogs. Across the web, you can find the answer to almost any R problem you encounter including questions about how to use specific packages and functions. The problem? This information is spread across the web on various threads, comment sections, and repositories making it hard for users to find and access this support. 

RDocumentation aggregates help documentation for R packages from CRANBioConductor, and GitHub - the three most common sources of current R documentation. It goes beyond simply aggregating this information, however, by bringing all of this documentation to your fingertips via the RDocumentaion package. The RDocumentation package overwrites the basic help functions from the utils package and gives you access to from the comfort of your RStudio IDE.

You can copy and paste the two lines of code below to install and load RDocumentation today:

Thanks for sharing.  Another good option is using, which uses a Google search that is limited to sites known to contain content relevant to R (including many beyond just these three).  Search results are provided all together, but there are 5 tabs that separate the results into the following categories:  support, books, articles, packages, and 'for beginners'.  I have found this an invaluable resource.
