R Project Updates

Updates from R Core:

• The declaratation of pythag() in Rmath.h has been removed - it has not been provided since R 2.14.0.

• C99 functions expm1, hypot and log1p are now required.

• R CMD INSTALL now correctly sets C++ compiler flags when all source files are in sub-directories of src.

• scale.default(x, center, scale) now also allows center or scale to be “numeric-alike”, i.e., such that as.numeric(.) coerces them correctly. This also eliminates a wrong error message in such cases.

Why do you build me up R CMD javareconf, baby
Just to let me down and mess me around?

And then worst of all, you never compile, baby
When you say you will#rstats

Heya #rstats dam, what is your favourite music to listen to while working? I find movie soundtracks pretty good for coding - Interstellar, TRON, Jurassic Park, and Lord of the Rings are some of my go tos - what am I missing out on?
