clipr_available: Is the system clipboard available?
Description
Checks to see if the system clipboard is write-able/read-able. This may be
useful if you are developing a package that relies on clipr and need
to ensure that it will skip tests on machines (e.g. CRAN, Travis) where
the system clipboard may not be available.
Usage
clipr_available()
dr_clipr()
Arguments
Value
clipr_available returns a boolean value.
dr_clipr prints an informative message to the console with
software and system configuration requirements if clipr is not available
(invisibly returns the same string)
