There are some highly productive researchers who have taken the time to write well constructed and very useable packages in R, married with meticulous documentation. The same individuals or groups of 1-3 people have also maintained said packages for 5 years or more, and regularly respond in person to queries. Two examples are ggplot2 and limma. To me, this is all the encouragement I need to use R.
