[Rd] PATCH: library(..., quietly=TRUE) still outputs "Loading required package: ..." (forgot to pass down 'quietly')
Calling library(..., quietly=TRUE) may still output:
Loading required package:
in some cases, e.g.
> library("R.utils", quietly=TRUE)
Loading required package: R.methodsS3
[...]
I traced this to base:::.getRequiredPackages2(), which forgets to pass
'quietly' to an internal library() call:
if (!attached) {
if (!quietly)
packageStartupMessage(gettextf("Loading required package: %s",
pkg), domain = NA)
library(pkg, character.only = TRUE, logical.return = TRUE,
lib.loc = lib.loc) || stop(gettextf("package %s could not be loaded",
sQuote(pkg)), call. = FALSE, domain = NA)
}
It's from that library() call the message is generated.
Here's a patch:
$ svn diff src\library\base\R\library.R
Index: src/library/base/R/library.R

I can submit it via http://bugs.r-project.org/ if preferred.

Parse error: I believe that this is intended to mean "Indexing matrices may not contain negative indices" not "You cannot use negative indices when indexing matrices". This is consistent with the help page: " A third form of indexing is via a numeric matrix with the one column for each dimension: each row of the index matrix then selects a single element of the array, and the result is a vector. Negative indices are not allowed in the index matrix.
