R Project Updates

Updates from R Core:

• 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.

• pretty(x, n=<large>) now works better (though it was never meant for large n); internally it uses the same rounding fuzz (1e-10) as seq.default() - as it did up to 2010-02-03 when both were 1e-7.

• arithmetic with zero-column data frames now works more consistently; issue raised by Bill Dunlap.

What #rstats tricks did it take you way too long to learn? One of mine is using readRDS and saveRDS instead of repeatedly loading from CSV
