Excellent R Code Format Package

(This article was first published on Quantitative Finance Collector, and kindly contributed to R-bloggers)

I have been looking for this type of package for several days, and luckily found it today. Unquestionable R is powerful, however, R programming is unfriendly as far as I concern, mainly due to the lack of format shortcut, which makes the R codes rather ugly. (It is an absolute advantage of Matlab, for example, ctrl+R for comment, ctrl+T for uncomment, ctrl+I for smart indent, etc.)

FormatR is the package for tidying R source code, although it is less convenient to use than the straightforward shortcuts in Matlab, this package is good enough for me, what is it for? as the title suggest:
Quotation
formatR: format R code automatically, farewell to ugly R code


Below is a comparison before and after using FormatR.
Before:
