Subject: is it a typo?

In ?options:

     'warning.expression': an R code expression to be called if a
          warning is generated, replacing the standard message.  If
          non-null is called irrespective of the value of option
          'warn'.

Is there a missing `it' between `non-null' and `is'?

Best,
Andy
