This group impresses me, so far I have been helped with all my questions
within 24 hours. Thanks.

Therefore another one.

I am used to programs (such as STATA) where observations with missing values
that are included in a model are simply ignored in the analysis. So far I
have not been able to figure out how to deal with missing values in R and
have solved the problem by deleting observations with missing values before
loading them into R.

Can anyone give me a hint on how to do this in a simpler way?
