By default the (arbitrary) signs of the loadings from
princomp()are chosen so the first element is non-negative.
If –default-packages is not used, then
Rscriptnow checks the environment variable R_SCRIPT_DEFAULT_PACKAGES. If this is set, then it takes precedence over R_DEFAULT_PACKAGES. If default packages are not specified on the command line or by one of these environment variables, then
Rscriptnow uses the same default packages as
R. For now, the previous behavior of not including methods can be restored by setting the environment variable R_SCRIPT_LEGACY to yes.
When a package is found more than once, the warning from
find.package(*, verbose=TRUE)lists all library locations.
POSIXt objects can now also be rounded or truncated to month or year.
