This PR fixes a bug during the step where the
gnm()function determines which coefficients to constrain based on the arguments to the function call. The original code askesif(res == 0 && length(constrain) == 1), which seems to be testing for the situation whereconstrainis a character vector of length 1 but does not match any of the existing coefficient names. However, when two or more coefficients to constrain are specified, then the result ofres == 0has a length greater than 1, and this causes either a warning or error (depending on the version of R, it seems?) when matched with the scalar "AND" operator&&. By usingidentical(res, 0)instead, we get around this issue.
