A general description is here.
[On Windows only], ‘writeClipboard(.., format = <n>)’ now does correctly pass ‘format’ to the underlying C code, thanks to a bug report (with patch) by Jenny Brian.
‘rbind.data.frame()’ allows to keep ‘<NA>’ levels from factor columns (PR#17562) via new option ‘factor.exclude’.
Additionally, it works in one more case with matrix-columns which had been reported on 2017-01-16 by Krzysztof Banas.
