R Project Updates

Updates from R Core:

• Reverted unintended change in behavior of return calls in on.exit expressions introduced by stack unwinding changes in R 3.3.0.

• approx(), spline(), splinefun() and approxfun() also work for long vectors.

• deparse() (and dump()) are more useful for S4 objects; dput() now using the same internal C code (instead of its previous imperfect workaround R code). More user visibly, dput(), etc now print the names() information only once, using the more readable (tag = value) syntax. These functions got a new (partly experimental) control option via .deparseOpts() "nice_names" which when set (e.g. as part of "all") also use the (tag = value) syntax for atomic vectors.

• (1:n)[-n] no longer segfaults for n <- 2.2e9 (on a platform with enough RAM).

• package.skeleton() gets optional encoding argument.

• Internal C-level R_check_class_and_super() and hence R_check_class_etc() now also consider non-direct super classes and hence return a match in more cases. This e.g., fixes behaviour of derived classes in package Matrix
