R Project Updates

Updates from R Core:

• CRAN Policy Change new rev3670

• R CMD INSTALL Windows .zip file obeys --lock and --pkglock flags.

• Evaluation of ..0 now signals an error. When ..1 is used and ... is empty, the error message is more appropriate now.

• New low level utilities ...elt(n) and ...length() for working with ... parts inside a function.

• isTRUE() is more tolerant and now true in x <- rlnorm(99); isTRUE(median(x) == quantile(x)["50%"]). New function isFALSE() defined analogously.

• The default symbol table size has been increased from 4119 to 49157; this may improve symbol resolution performance when many packages are loaded.
