R Project Updates

Updates from R Core:

• R CMD INSTALL <pkg> now produces the intended error message when, e.g., the LazyData field is invalid.

• dput(), deparse() and dump() now print the names() information only once, using the more readable (tag = value) syntax, notably for list()s, i.e., including data frames.

• These functions gain a new control option "niceNames" (see .deparseOpts()), which when set (as by default) also uses the (tag = value) syntax for atomic vectors. OTOH, without deparse options "showAttributes" and "niceNames", names are no longer shown also for lists. as.character(list( c (one = 1))) now shows the name as as.character(list(list(one = 1))) has always done.

• m:n now also deparses nicely when m > n.

• mclapply, pvec and mcparallel (when mccollect is used to collect results) no longer leave zombie processes behind.

• Subassignment with zero length vectors now coerces as documented.
