This blog is updated daily.
A general description is here.
The new ‘unirootS()’ function is a ‘safe’ version of ‘uniroot()’ auto-extending the search interval when needed.
‘str(x)’ is considerably faster for very large lists, or factors with 100,000 levels, the latter as in PR#15337.
‘checkFF()’ (used by ‘R CMD check’) does a better job of detecting calls from other packages, including not reporting those where a function has been copied from another namespace (e.g. as a default method). It now reports calls where ‘.NAME’ is a symbol registered in another package.
‘qr.coef()’ and related functions did not properly coerce real vectors to complex when necessary. (PR#15332)
