This blog is updated daily.
A general description is here.
‘arrayInd(*, useNames=TRUE)’ and, analogously, ‘which(*, arr.ind=TRUE)’ now make use of ‘names(.dimnames)’ when available.
‘load()’ now has a ‘verbose’ argument for debugging support, to print the names of objects just before loading them.
‘chol(pivot = TRUE, LINPACK = TRUE)’ is defunct.
Arguments ‘EISPACK’ for ‘eigen()’ and ‘LINPACK’ for ‘chol()’, ‘chol2inv()’, ‘solve()’ and ‘svd()’ are ignored: LAPACK is always used.
If ‘x’ is a symbol, ‘is.vector(x, "name")’ now returns ‘TRUE’, since ‘"name"’ and ‘"symbol"’ should be synonyms. (Reported by Hervé Pagès.)
