The R logo has been revised in to be more compatible with the principles
of flat design followed by some recent user interfaces such as Microsoft
Windows >= 8 and Mac OS X >= 10.10 (Yosemite). The new logo is
available for download from the R project web site in SVG and
high-resolution PNG formats:

design skills.
