Convert a Formula Transformed by denumerate

DESCRIPTION:

denumerate converts a formula written using the conventions of loglm into one that terms is able to process. renumerate converts it back again to a form like the original.

USAGE:

renumerate(x)

REQUIRED ARGUMENTS:

x
A formula, normally as modified by denumerate.

VALUE:

A formula where all variables with names of the form .vn , where n is an integer, converted to numbers, n , as allowed by the formula conventions of loglm.

SIDE EFFECTS:

None.

DETAILS:

This is an inverse function to denumerate . It is only needed since terms returns an expanded form of the original formula where the non-marginal terms are exposed. This expanded form is mapped back into a form corresponding to the one that the user originally supplied.

EXAMPLES:

denumerate(~(1+2+3)^3 + a/b)
