R Project Updates

Updates from R Core.

• table(x, exclude=NULL) now sets useNA = "ifany" (instead of "always"). Together with the bug fixes for this case, this recovers more consistent behaviour, also compatible to older versions of R. As a consequence, summary() for a logical vector no longer reports (zero) counts for NA when there are no NAs.

• The plot() method for ppr() has enhanced default labels (xmin and main).

• str(x)’s default method is more “accurate” and hence somewhat more generous in displaying character vectors; this will occasionally change R outputs (and need changes to some *.Rout(.save) files).

• [In progress.] configure looks for a flag for the C++ compiler which approximates C++98/C++03 compliance, and uses it as part of the CXX98 macro in file etc/Makeconf. For example, -std=gnu++98 is selected for g++ 6.x.

• There is a new macro CXXSTD to help specify the standard for C++ code, e.g. -std=c++98. This makes it easier to work with compilers which default to a later standard: for example, with CXX=g++6 CXXSTD=-std=c++98 configure will select commands for g++ 6.x which conform to C++11 and C++14 where specified but otherwise use C++98.

• readline headers (and not just the library) are required unless configuring with --with-readline=no.

• configure checks for the required header sys/select.h (or sys/time.h on legacy systems) and system call select and aborts if they are not found.

Quote of the Week

.@drob has zero natural talent - should not be coding. His analysis is bad & his ggplot2 ability-zilch! https://t.co/WTWN3vCpVz
