[R] Set a Numeric Field To Blank

[Sparks, John James]

Hi,

I have one of those questions that I suspect is very simple, but hard to
classify, so I have been searching for quite some time and am not able to
find it.

If I have a data frame and I want to change all the values of one of the
columns to blanks, what is the syntax?  I tried a few different spellings
of Null, etc., but can't get it.  Can someone please send me what I
suspect is a one line solution to this?

Many thanks,
