Looks like there is a buglet in 'installed.packages', around line 17:
for (lib in lib.loc) {
dest <- file.path(tempdir(), paste("libloc_", URLencode(lib,=20
TRUE), paste(fields, collapse =3D ","), ".rds", sep =3D ""))
if (!noCache && file.exists(dest) && file.info(dest)$mtime >=20
file.info(lib.loc)$mtime) {
^^^^^^^
=20
The 'lib.loc' should be 'lib', otherwise the comparison is always against t=
he first library in 'lib.loc', not against the one being checked. [Normally=
the multiple test in '>' would flag a warning from 'if', but the &&s mean =
that only the first element is used.]
I can't provide a reproducible example for this, because it's so installati=
on-dependent.
Still present in R-devel from 8th March.
