  • cleanNLP 2.0.3 - cleanNLP is designed to make it as painless as possible to turn raw text into feature-rich data frames. The updated version includes a new backend (udpipe) for part of speech tags and parsing with no external dependencies. See the cleanNLP 2.0: Quickstart Guide for more details.

R Project Updates

Updates from R Core:

  • parallel::detectCores(logical = FALSE) should be more reliable on multi-CPU Linux systems, especially with virtualized OSes.

  • is.na(NULL) no longer warns. (PR#16107)

  • By default, packages are now byte-compiled on installation.

  • POSIXt objects can now also be rounded or truncated to month or year.

  • stopIfnot() is a new alternative to stopifnot(), nicer to use when testing several expressions in one call.

  • By default, packages are now byte-compiled on installation.

  • 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.)
