locateExecutable(fileName, errorIfMissing = TRUE)

Arguments

executable, fileName
Name of the executable to run.
paramString
A character string giving the parameters to pass to the executable, if any.
errorOnFail, errorIfMissing
Logical value: should an error be produced if the executable can't be found?

...
Additional arguments to system.

  • For execute, the return value of the underlying call to system. For locateExecutable, the location of the requested executable, or NULL if it could not be found.
