CRAN

• rsMove - Supporting animal movement ecologist in handling remote sensing data and in combining it with animal movement data.

• Dec 2017: “Top 40” New Package Picks

GitHub only

• knitrProgressBar - Provides a progress bar that can write to a variety of locations, including stdout, stderr, or a file. Useful when using knitr or rmarkdown::render and you still want to see progress of calculations in the terminal.

Package Releases

• listenv 0.7.0 - List environments are environments that have list-like properties. Now with copy-free dropping of elements and convient setup of listenv matrices and arrays.

• srvyr 0.3.0 - srvyr is a wrapper around the survey package that lets you analyze complex survey data using dplyr’s grammar. It’s been updated to use dplyr’s new non-standard evaluation style and have faster and less buggy database support.

• 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.

• Rcpp 0.12.15 - Numerous tweaks and enhancements

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.)
