run_onload: Run .onLoad if needed
Description
This is run before copying objects from the namespace to
the package environment. In a normal install + load, the
namespace would be locked between these stages, but we
don't do that with load_all.Usage
run_onload(pkg = ".")
Arguments
pkg
package description, can be path or package
name. See as.package for more information Details
A variable called onLoad is created in the
package's devtools metdata to indicate that it's
attached.
