No, the coordinates aren't weighted. They're the standard DW-NOMINATE coordinates, which are scaled to fit between -1 and 1 (more or less).
Right now the function doesn't return the weight parameter, but I agree that it should and it shouldn't be hard to add that feature. I'll see if I can do this in the next couple of days.

I have been following the instructions laid out in the book "Analyzing Spatial Models of Choice and Judgment with R," written by Armstrong et al. (2014). On pages 203-204 they show a procedure for estimating cutting lines that includes the use of the weight paramenter.

Sorry to bother you again, but would it also be possible to make the function return the beta parameter as well when you modify it?
Thanks and best,

I'm returning the values in the same format as wnominate's nomObject, so with a bit of finagling the results can be used with wnominate::plot.coords
:
class(dwnom_result) <- "nomObject"
wnominate::plot.coords(dwnom_result)
