5 years ago - The new function asplit() allow splitting an array or matrix by its margins.
- Experimentally, setting environment variable _R_CHECK_LENGTH_1LOGIC2 will lead to warnings (or errors if the variable is set to a ‘true’ value) when && or || encounter and use arguments of length more than one.
- convertColor() is now vectorized, so a lot faster for converting many colours at once. The new argument vectorized to colorConverter() ensures that non-vectorized colour converters still work. (Thanks to Brodie Gaslam.)
- Performance of substr() and substring() has been improved. (but how much, faintly recall not much)
- stopifnot() has been simplified thanks to Suharto Anggono's proposals to become considerably faster for cheap expressions. (this is a big deal)
- substr() and substring() now signal an error when the input is invalid UTF-8.
- Fixes to convertColor() for chromatic adaptation; thanks to Brodie Gaslam PR#17473.
- Class unions are unloaded when their namespace is unloaded (PR#17531, adapted from a patch by Brodie Gaslam).
