[Rd] memory.limit(): Typo in Windows NEWS and function returns a "disregarded" error
Dear list subscriber (R-Core), there is a minor typo in the Windows specific NEWS for R 2.9.0: http://cran.at.r-project.org/bin/windows/base/CHANGES.R-2.9.0 There is no function 'memory.limits() but memory.limit() (see below). Secondly, I am kind of irritated by the function's behaviour. It returns an Error, but as it seems the memory limit is set according to the numeric value for the size argument even it is not a numeric-value according to the error message? In R 2.8.1 this error was not returned (see below). A clarification/explanation is most welcome.
