**R** is an extremely usefulÂ software environment for statistical computing and graphics. But as awesome as it is, it can be quite daunting to find just the right package for a specific task. Well, CRAN Task Views is designed to help alleviate this challenge. The table below is matches the task (right) with the package (left). While a bit primitive, it as quick reference it does work.

**F**or those that are must more industrious, check out “Visualizing the CRAN: Graphing Package Dependencies.” The authors uses graphÂ visualize the relationship between packages in CRAN. His analysis shows thatÂ MASS is the most “depended on” package on the CRAN. Â A total of 294 of the 3794 packages (almost 8%) in the CRAN depend on MASS. Â An additional 95 suggest MASS; so just over 10% of all R packages either suggest or depend on MASS.
