Hi, I'm stuck.  I am using a function called col_concat from the package
{assertr}.  But when I list it as a dependency, either by

import(assertr)

or

importFrom("assertr", "col_concat")

-----------

I get this error message:

* checking package dependencies ... ERROR

Namespace dependency not required: ?assertr?

See section ?The DESCRIPTION file? in the ?Writing R Extensions?

manual.

* DONE

Status: 1 ERROR
?------------
And when I take it out, I get a complaint that col_concat has no global
definition.

What???

Thanks,
?

Edit your DESCRIPTION file to include

imports: assertr

That?s why you get the "not required" message.

Thanks Bryan.  All of my imports are in the namespace.  Can you tell me why
this one should be in the description file?

Because you need an entry in the DESCRIPTION file _and_ an entry in NAMESPACE.
