[R] Switch Help

[Henrique Dallazuanna]

If you want type twice commands in function aar, you could try this:

aar <-function(command) {
	switch(command,
	 scrn = cat("scrn  :Screening","\n"),
	 dx = cat("dx    :Diagnosis","\n"),
	 df = cat("df    :Don't Forget","\n"))
}

invisible(Vectorize(aar)(c('dx', 'df')))
