First of all, you might try reading the manual.
Second, you might try something like this:
calculate <- function(x,y)
{
z <- x + y z
}
recalculate(z)
{
a <- z^2
a
}
z <- calculate(x, y)
recalculate(z)
You need to return some value from your functions,
and you need to assign that value to a variable.
