R Project Updates

Updates from R Core:

• Improved performance and robustness of matrix multiplication using BLAS: DGEMV is now used instead of DGEMM for matrix/vector and vector/matrix multiplication, DGEMM/DGEMV is bypassed when the input has NaN or Inf values, and performance for these input checks has been improved.

• qbeta() underflowed too early in some very asymmetric cases. (PR#17178)

• tapply() gets new option default = NA allowing to change the previously hardcoded value.

• R CMD build no longer wraps a BugReports field containing a long URL, which made it unusable in R <= 3.3.2.

• read.dcf() now consistently interprets any whitespace to be stripped to include newlines.

• str() no longer shows "list output truncated", in cases that list was not shown at all. Thanks to Neal Fultz (PR#17219)
