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
…
Pass other options to write_clip. Generally only used to
pass the argument allow_non_interactive_use = TRUE.
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)
Details
If you are trying to call this in a non-interactive session, be sure to call
using clipr_available(allow_non_interactive = TRUE), or by setting the
environemnt variable CLIPBOARD_AVAILABLE=TRUE
