The cluster package, maintained by Dr. Martin Mächler, includes a variety of methods for cluster analysis including functions for hierarchical clustering, creating AGNES objects, clustering large applications and more. Check out the cluster package’s page on Rdocumentation.org to learn more and use it for your own R projects!
5. ggplot2, An implementation of the grammar of graphics in R
One of the most popular R packages for data visualization is ggplot2. This useful data visualization package had 72,550 monthly direct downloads. Authored by Hadley Wickham, the ggplot2 package offers an easy, consistent interface for producing plots and charts in R. As mentioned in its documentation, “it combines the advantages of both base and lattice graphics: conditioning and shared axes are handled automatically, and you can still build up a plot step by step from multiple data sources. It also implements a sophisticated multidimensional conditioning system and a consistent interface to map data to aesthetic attributes.” Want to learn for yourself? DataCamp offers 3 full-length courses devoted to ggplot2:
- Data Visualization with ggplot2 (Part 1)
- Data Visualization with ggplot2 (Part 2)
- Data Visualization with ggplot2 (Part 3)
*Rankings are based on direct downloads, as opposed to indirect downloads related to dependencies. Direct downloads were measured as of 11/04/2016. Please note these numbers can fluctuate daily.
RDocumentation aggregates help documentation for R packages from CRAN, BioConductor, and GitHub – the three most common sources of current R documentation. RDocumentation.org 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 RDocumentation.org from the comfort of your RStudio IDE. Look up the newest and most popular R packages, search through documentation and post community examples.
