R Project Updates

Updates from R Core:

  • configure will use pkg-config to find the flags to link to jpeg if available (as it should be for the recently-released jpeg-9c and libjpeg-turbo). (This amends the code added in R 3.3.0 as the module name in jpeg-9c is not what that tested for.)

  • The duplicated() method for data frames is now based on lists (instead of string coercion). Consequently unique() is better distinguishing data frame rows, fixing PR#17369 and PR#17381.

  • Calling names() on an S4 object derived from "environment" behaves (by default) like calling names() on an ordinary environment.

  • The environment variable R_MAX_VZISE can now be used to specify the maximal vector heap size. On macOS, unless specified by this environment variable, the maximal vector heap size is set to the maximum on 16GB and the available physical memory. This is to avoid having the R process killed when macOS over-commits memory.
