[R-pkg-devel] dependencies

[Cathy Lee Gierke]

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,
​
