I think you're supposed to skip the example (throwing a warning, if
you like ...) if rgl isn't available, rather than throwing an error ... ?

This concerns packages: ...
Suggested packages should be used conditionally: see �1.1.3.1 of 'Writing
R Extensions'. Some of these are hard to install on a platform without X11
such as M1 Macs: see the logs at https://www.stats.ox.ac.uk/pub/bdr/M1mac/.
You can check all of the suggested packages by setting environment
variable _R_CHECK_DEPENDS_ONLY_=true -- see
https://cran.r-project.org/doc/manuals/r-devel/R-ints.html#Tools .
Is this a false alarm?
In each case, the outfile contains:
* checking package namespace information ... OK
* checking package dependencies ... NOTE
Package suggested but not available for checking: 'rgl'
indicating that rgl is not avaiable on the testing machine. Then, when
checking examples an error is triggered
when an example calls something that requires rgl.

Loading required namespace: rgl
Failed with error: 'there is no package called 'rgl''
Error in heplot3d.mlm(Adopted.mod, hypotheses = list(Reg = c("AMED",
"BMIQ")), :
rgl package is required.
Calls: heplot3d -> heplot3d.mlm
Execution halted
Yet, heplot3d seems to contain the required way to refer to the suggested rgl
package:
if (!requireNamespace("rgl")) stop("rgl package is required.")
So, I'm mystified. Can anyone help?
