but after some thinking I realized that it would indeed be a better idea (less to type?) to have \useGNUPLOTgraphic[name][1,3] and \useGNUPLOTgraphic[name][1,3][width=.9\textwidth] instead.

At the beginning the main reason against it was that I didn't know how to distinguish which kind of parameters are being used in the second pair of brackets, but I guess that I can safely use \ifnumberelse as a test on the first item to distinguish between the two.

Maybe you could play only with the parameter count. The limitation is that an empty second argument is required when only options need to be passed.

why? in that case #3 is empty and #2 contains the options

Hm, I thought that the initial goal was to know if the parameter passed is a number list, or an option list. In the suggested code, the assumption is that the number list (if any) is always the second parameter.

If not, how to handle those cases?

\useGNUPLOTgraphic[name][2,3,5] \useGNUPLOTgraphic[name][width=2in]

But I guess there are clever internal macros that could help :-)
