The easiest way out, e.g. for a lecture, is to use options(digits=x), which
is global but can be reset. Otherwise, you could assign a class to your
returned output, and define print.myclass. Probably a bit too much work for
what you want to achieve. See, for example, the code of  print.htest.

eg <- function(x, digits=4) {
  xbar <- mean(x)
  sdx <- sd(x)
  value <- list(xbar, sdx)
  names(value) <- c("Mean of X", "SD of X")
  value
}
options(digits=2)
eg(rnorm(10))
