[R] Pasting function arguments and strings

[William Dunlap]

Is this the sort of thing you are looking for?

  > f <- function(testName, dataset, ...) {
  +     testFunc <- match.fun(paste(testName, "_test", sep=""))
  +     testFunc(dataset, ...)
  + }
  > m_test <- function(x) "the m test"
  > p_test <- function(x) "the p test"
  > f("m", 17)
  [1] "the m test"
