R Project Updates

Updates from R Core:

• lower.tri(x) and upper.tri(x) only needing dim(x) now work via new .row() .col() and no longer call as.matrix() by default in order to work efficiently for all kind of matrix-like objects.

• type.convert() becomes a generic, with additional methods that operate recursively over list and data.frame objects. Courtesy of Arni Magnusson (PR#17269).

• Setting options(device = *) to an invalid function no longer segfaults when plotting is initiated. (PR#15883)

• encodeString(<very large string>) no longer segfaults. (PR#15885)

• Construction of names() for very large objects in c() and unlist() now works, thanks to Suharto Anggono’s patch proposals in PR#17292.

• callNextMethod() works for ... methods.

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