R Project Updates

Updates from R Core.

• ppr() and supsmu() get an optional trace argument, and ppr(.., sm.method=..spline) is no longer limited to sample size n <= 2500.

• smooth.spline() now allows direct specification of lambda, gets a hatvalues() method and keeps tol in the result, and optionally parts of the internal matrix computations.

• split(<very_long>, *) now works even when the split off parts are long.

• min() and max() now also work correctly when the argument list starts with character(0).

• R CMD build now preserves dates when it copies files in preparing the tarball.

• Headers R_ext/BLAS.h and R_ext/Lapack.h have many improved declarations including const for double-precision complex routines. Inter alia this avoids warnings when passing string literal arguments from C++11 code.

• formatC(x, flag=f) allows two new flags, and signals an error for invalid flags also in the case of character formatting.

Upcoming Events

• rstudio::conf 2017 January 13 and 14, 2017
