The execute function is a wrapper around the system2
function in base, which additionally echoes the command being run (including
the full path to the executable) if the reportr output level is
Debug. locateExecutable simply returns the path to an
executable file on the system PATH.
locateExecutable(fileName, errorIfMissing = TRUE)execute(executable, params = NULL, errorOnFail = TRUE, silent = FALSE,
...)
For execute, the return value of the underlying call to
system2. For locateExecutable, the location of the
requested executable, or NULL if it could not be found.
Name of the executable to run.
A character vector giving the parameters to pass to the executable, if any. Elements will be separated by a space.
Logical value: should an error be produced if the executable can't be found?
Logical value: should the executable be run without any output?
Additional arguments to system.
