R-2.2.0 is released
...ned char *
rather than as SEXPs. (Wish of Keith Frost, PR#7853)
o The search for symbols in a .C/.Call/... call without a
package argument now searches for an enclosing namespace and
so finds functions defined within functions in a namespace.
o R_max_col() has new (5th) argument '*ties_meth' allowing
non-random behavior in the case of ties.
o The header files have been rationalized: the BLAS routine
LSAME is now declared in BLAS.h not Linpack.h, Applic.h no
longer duplicates routines from Linpack.h, and Applic.h is
divided into API and non-API sections.
