That is great!
Is there a way to know version required in the dependent packages?

$lme4

[7] "utils" "parallel" "MASS" "lattice" "boot" "nlme"

Use reverse=TRUE to list packages that depend on the given package.

Hi
Is there an elegant way to recursive list all dependencies of a package prior
to its installation or upgrade?
I am particularly interested in finding which of the packages currently
installed in my test/production environment would require an upgrade prior to
actual installation/upgrade of a package.
Can the packrat package help with this?
Thank you
