No. R functions usually react to NA with correct and in help pages 
specified ways. I do not know which functions you used and how. You still 
fail to provide any reasonable info.

Without context I recall that you used some kind of regression. How do you 
suppose any regression or model can be executed if variables have 
different length?

That is why there are missing values used. And regressins can usually 
handle missing values based on na.action parameter value smoothly. At 
least for me and for thousands of R users for more than 10 years. 
Therefore I suspect that problem is either in your data or in the way you 
use them.

But if you fail to provide some code and data you stay alone for resolving 
your problems.
