This blog is updated daily.
A general description is here.
‘parallel::detectCores()’ is now able to find the number of physical cores (rather than CPUs) on Sparc Solaris.
It can also do so on most versions of Windows; however the default remains ‘detectCores(logical = TRUE)’ on that platform.
Reference classes now keep a record of which fields are locked. ‘$lock()’ with no arguments returns the names of the locked fields.
The creation of ticks on log axes (including ‘axTicks()’ sometimes
incorrectly omitted a tick at one end
‘mapply()’ now gives an explicit error message (rather than an obscure one) if inputs of zero and positive length are mixed.
