But what's a "NA" value in general? Is 0 always a meaningful value as numeric? Context-sensitive..
NA is a logical constant of length 1 which contains a missing value indicator. Whether or not 0 is a meaningful value as numeric depends on your data and the questions you are asking of it. You don't ask this question, but if I read this thread correctly and you are trying to workaround a data input problem with R in Org-babel, then replacing missing values with 0 in a numeric context to get around the Org-babel problem is NOT a good idea.
