[R] Printing contents of a variable

[darnold]

All,

Can someone explain why this does not print the contents of x when I source
this file?

CoinTosses <- function(n,print=TRUE) {
  x <- sample(c(0,1), n, replace=TRUE)
  y <- x
  y[y==0] <- "T"
  y[y==1] <- "H"
  p <- sum(x)/n
  p
}

x <- CoinTosses(40)
x

On the other hand, if I source this file:

CoinTosses <- function(n,print=TRUE) {
  x <- sample(c(0,1), n, replace=TRUE)
  y <- x
  y[y==0] <- "T"
  y[y==1] <- "H"
  p <- sum(x)/n
  p
}

Then run at the command line:

x <- CoinTosses(40)
x

The result is:

> x <- CoinTosses(40)
> x
[1] 0.475

Not sure why the former does not display the contents of x.

Thanks.

D.
