Setting a cells formula using the FormulaR1C1 command will have no
effect on the rest of the workbook. I use this style quite often to
achieve dynamic ranges.

I've always used A1 reference style in all my code, formulas, etc. I guess
my brain is just wrapped that way.

Now I need to use VBA code to insert an array formula, because the source
ranges are changed when new data are added, and I need to reset the array
formula to the original ranges again. however, my A1 notation doesn't play
well with FormulaArray.

Is there an alternative? Or, if I use R1C1 notation for just this formula,
will that affect anything else in the workbook?

Should I set my array formulas to use named ranges instead of straight
worksheet references, and use VBA to refresh the named ranges instead?

Thanks!
