[R] Error Calculating Mean

I have a vector containing players' weights.  When I enter

"numeric" is returned.

When I type mean(data.linear$Weight)

NA is returned.

Any ideas as to why this may be the case?  I am trying to calculate
this ultimately so I can superimpose a normal density line over a
histogram containing the weights?
