R Project Updates

Updates from R Core:

• As an experimental feature, when codeloadNamespace fails because the requested package is not available the error is initially signaled with a retry_loadNamespace restart available. This allows a calling handler to try to install the package and continue.

• var(f) and hence sd(f) now give an error for factor arguments; they gave a warning since R 3.2.3, PR#16564.

• next(n) now also works for larger n and no longer loops infinitely for e.g, n <- 214e7.

• Many package not found errors are now signaled as errors of class packageNotFoundError.

• Fork cluster could hang due to a race condition in cluster initialization (makeCluster()).

• .Deprecated now signals a warning of class deprecatedWarning, and .Defunct now signals an error of class defunctError.

• New functions errorCondition and warningCondition provide a convenient way to create structured error and warning objects.

• On Windows, socketSelect would hang with more than 64 sockets, and hence parallel::clusterApplyLB would hang with more than 64 workers.
