dot-onLoad: Package startup hook
In ETRep: Analysis of Elliptical Tubes Under the Relative Curvature Condition
.onLoad R Documentation
Package startup hook
Description
This special function is called automatically when the ETRep package is loaded.
It ensures that 'rgl' uses the off-screen WebGL device ('useNULL = TRUE')
on macOS and other headless environments, so that package installation
and examples do not fail with an OpenGL error.
Usage
.onLoad(libname, pkgname)
Arguments
libname
Character string; the path to the package library.
pkgname
Character string; the name of the package.
If the user has not already set 'options(rgl.useNULL)', this function sets it
to 'TRUE' to suppress the typical warning:
"rgl.init failed, will use the null device".
