R Project Updates

Updates from R Core:

• grep(perl = TRUE) and friends set a maximal recursion limit, taking into account R’s estimate of the remaining C stack space. This reduces the chance of C stack overflow, but because it is conservative may return a non-match with a warning in examples that succeeded before.

• The deprecated support for PCRE versions older than 8.20 will be removed in R 3.4.1. (Versions 8.20-8.31 will still be accepted but deprecated.)

• getGraphicsEvent() now works on X11(type="cairo") devices. Thanks to Frederick Eaton (for reviving an earlier patch).

• There is a new argument onIdle for getGraphicsEvent(), which allows an R function to be run whenever there are no pending graphics events. This is currently only supported on X11 devices. Thanks to Frederick Eaton.
