You might want to look at rm to see how that function handles the
problem.

I want to write:
zap <- function(v) {
if (exists(v)) {rm(v)}

But of course this doesn't work because the rm() acts on v which is
within zap() and doesn't affect the parent environment:
x <- 1
zap("x")
x
[1] 1
How would I make this zap() function work?
