rgl.useNULL

0th

Percentile

Report default use of null device.

This function checks the "rgl.useNULL" option if present, or the RGL_USE_NULL environment variable if it is not. If the value is TRUE or a string which matches yes or true in a case-insensitive test, TRUE is returned.

Usage
rgl.useNULL()
Value

  • A logical value indicating the current default for use of the null device.

Note

This function is checked by the initialization code when rgl is loaded. Thus if you want to run rgl on a system where there is no graphics support, you should run options(rgl.useNULL = TRUE) or set the environment variable RGL_USE_NULL=TRUE *before* calling library(rgl) (or other code that loads rgl), and it will not fail in its attempt at initialization.
