Check whether current R session supports X11 or not.

Contrary to capabilities("X11") which only checks for X11 support on startup [1], this function checks whether X11 is supported when it is called. This is done by querying a temporary R session.

capabilitiesX11(reset=FALSE, ...)

Arguments

reset

If TRUE, any previously obtained results are ignored, otherwise not.

...

(optional) character strings of command-line options to Rscript.

Value

Returns TRUE if X11 is supported, otherwise FALSE.
