Move un-imported packages to "Suggests"?

[trevorld]

• Some of your packages in your Imports seem to be used only in your Examples, Tests, and Vignettes. It might be better to move these to Suggests so downstream packages don't need to install them when installing {truchet} (such as when doing Continuous Integration testing). When used in Examples, Tests, Vignettes you'd need to guard their usage with requireNamespace() blocks (or add them to the VignetteBuilder field in DESCRIPTION)...
• In particular, in the future if {truchet} is published to CRAN I may try to Import/Suggest {truchet} to make some {grid} graphics using sf::st_as_grob() and your {ggplot2} Imports seems to be a non-trivial dependency to download that doesn't seem to be an actual dependency for {truchet} but only used in its examples/vignettes...

Thank you for this. I am relatively new at package development and was not sure about the package used in the articles/vignettes, but I think this has been resolved. Check the DESCRIPTION file.

Thanks!

If you put packages like {ggplot2} in VignetteBuilder you don't need a bunch of requireNamespace("ggplot") in your vignettes checking if {ggplot2} is available. (You always need {knitr} in there). CRAN has a test where they test your package without any Suggested packages installed...
