You say "adjusting the current", and according to your
prior paragraph, this is done by adjusting the resistance.
So this seems to support what I said in my original post,
that you can only manipulate R and V directly (not I).
Hence, V and R are the independent variables, and I is the
dependent variable.

So in the "iterative equation" view of a circuit, you
start with an "initial value" for R and V, which results
in a value for I, which influences R and V, etc., until a steady state is reached.  No?
