recode vector values to NA

Greetings,

I'm in the painful process of migrating from SAS to R.  In the process I've
discovered that there are some basic things that I am getting hung up on.  The
most basic is the simple recoding of variables.  Suppose I create a vector

  x <- rnorm(10000)

and I want to recode all values of x > 1.5 to NA.  How would I do that in R?

x[x > 1.5] <- NA
