R Project Updates

Updates from R Core.

• The tests for C++11 compliance are now much more comprehensive.
• configure checks if the compiler specified by CXX CXXFLAGS is able to compile C++ code.
• 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: 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.
• Support for the defunct IRIX and OSF/1 OSes and Alpha CPU has been removed.
• table() no longer drops an NaN factor level, and better obeys exclude = <chr>
• merge(df1, df2) now also works for data frames with column names na.last, decreasing, or method.

#SPSS comes with a huge manual that is like "The Art of the Deal" for stats. Dopey #Rstats users don't have. Sad! https://t.co/IFWumd9oxZ
