Achim suggested using explicitly rgl:: everywhere. That's quite ugly,

I think you do want Depends rather than Suggests here. Suggests is
for when the other package does not need to be loaded for the user to
use your package, but the other package might be used in an example or
vignette.
In your package, the default method for a generic function that your
package defines calls functions from rgl. To me that means rgl should be
in Depends, and the required functions from rgl should be imported in
the NAMESPACE file.

[Rd] 'library' or 'require' call not declared from: 'rgl'
I'm checking a new release of vcdExtra via win builder with R-devel 2014-10-29 r66897 and have run into a Warning I don't know how to fix. I have one S3 generic, mosaic3d() that uses rgl and don't want to have rgl always loaded via Depends:. Instead, the mosaic3d.default() method includes if (!require(rgl)) stop(rgl is required) This always worked in the past, but in this testing cycle, I got a slew of no visible global function definition for ... all rgl functions. I revised DESCRIPTION to include: Imports: rgl and NAMESPACE: import(rgl) All the no visible global function definition ... went away, but I'm stuck with * checking dependencies in R code ... WARNING 'library' or 'require' call not declared from: 'rgl' See the information on DESCRIPTION files in the chapter 'Creating R packages' of the 'Writing R Extensions' manual. How can I solve this? -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept.
