turning the non-zeros of a vector into 1's

suppose I create the following vector:

x = rbind(1, 3, 5, 0, 7, 8, 0, 4, 5, 0, 8)
x

I want to turn the non-zeros into ones:

for (   i in 1:length(x)   ){
if (x[i]!=0)   x[i] = 1}
x

This works fine, but I was wondering if anyone out there can think of a mathematical way of doing this operation instead of using the if statement.
