Hmm... do something like that, no need to change the global option (I used a
named vector instead of a list, it's more convenient):
eg <- function(x, digits=4) {
xbar <- mean(x)
sdx <- sd(x)
value <- c(xbar, sdx)
names(value) <- c("Mean of X", "SD of X")
print(round(value,digits));
return(invisible(value))}
