R Project Updates

Updates from R Core:

• qr.coef(qd, y) now has correct names also when qd is a complex QR or stems from qr(*, LAPACK=TRUE).

• hist(x, "FD") no longer “dies” with a somewhat cryptic error message when x has extreme outliers or IQR() zero: nclass.FD(x) tries harder to find a robust bin width h in the latter case, and hist.default(*, breaks) now checks and corrects a too large breaks number.

• methods:::cbind() and methods:::rbind() avoid deep recursion, thanks to Suharto Anggono

• sigma(fm) now takes the correct denominator degrees of freedom for a fitted model with NA coefficients.

• model.matrix(~1, mf) now gets the row names from mf also when they differ from 1:nrow(mf), thanks to the suggestion by Sebastian Meyer.

• Attempting to increase the length of a variable containing NULL using length()<- still has no effect on the target variable, but now triggers a warning.

• Resource leaks reported by Steve Grubb fixed.

• Construction of names() for very large objects in c() and unlist() now works, thanks to Suharto Anggono’s patch proposals.
