R Project Updates

Updates from R Core.

• summary.default() no longer rounds, but its print method does, resulting in much less extraneous rounding notably of numbers in the ten thousands.

• R CMD check reports more dubious flags in files ‘src/Makevars[.in]’, including -w and -g.

• R CMD check has been set up to filter important warnings from recent versions of gfortran with -Wall -pedantic: this now reports non-portable GNU extensions such as out-of-order declarations.

• system.time() now uses ‘message()’ instead of ‘cat()’ when terminated early, such that ‘suppressMessages()’ has an effect; suggested by Ben Bolker.

Upcoming Events

• satRday! in Budapest, Hungary 3 September
  The satRdays are SQLSaturday-inspired, community-led, one-day, regional and very affordable conferences around the world to support collaboration, networking and innovation within the R community.
