[R] Summing with NA

[tj]

Hi all,
May I request for your help if you have time and if you have an idea on how
to do this.  I want to add three vectors... And my goal is to obtain the sum
of the vectors, ignoring the vector of "na"... 

Here is what i did in R.. I'm adding the three vectors, e,z,k, and my
objective is to get an answer = -23.
I tried putting the na.omit but it did not work.  Thanks.

> z
[1] -12  -9
> e
[1] -2  0
> k
[1] NA NA
> sum(z+e+k)
[1] NA
>
