Not quite sure what you mean with "dealing with NAs in use-specific code".
Some functions handle these automatically, like lm(). If you write your
own code, and want to handle NA-s somehow, you have to implement such
checks yourself. You may also use the "complete.cases" function (but that

Well..
1) To add to Duncan's comments, if you create a new "dataset" discrete
factor column to indicate the dataset in the combined data, then you
would fit the model dataset/(corrected denominator).

more than a "few" data sets, s
You can put all your data in one data.frame along with a column called, say,
