R Project Updates

Updates from R Core.

• There is support for compiling C++14 code in packages on suitable platforms: see Writing R Extensions for how to request this.

• configure now adds a compiler switch for C++11 code, even if the compiler supports C++11 by default. (This ensures that gcc 6.x uses C++11 mode and not its default C++14 mode.)

• configure now tests for a C++14-compliant compiler by testing some basic features. This by default tries flags for the compiler specified by CXX, but an alternative compiler, options and standard can be specified by variables CXX1Y, CXX1YFLAGS and CXX1YSTD (e.g., -std=gnu++14).

• Speedup in simplify2array() and hence sapply() and mapply() (for the case of names and common length > 1), thanks to Suharto Anggono’s PR#17118.

• The default and data.frame methods for stack() preserve the names of empty elements in the levels of the ind column of the return value. Set the new drop argument to TRUE for the previous behavior.

Quote of the Week

When Mexico sends its scientists, they’re not sending the best. They’re bringing #Rstats. They’re bringing data. They’re Bayesians.
