I'm trying to get significance of coefficients as for lm() but I news help.
In order for there to be significance tests for the coefficients, the problem would needs to be embedded in some sort of a probability model. Such may be possible, ... but it is not immediately apparent to me how that would be done. With lm() you are comparing the estimated coefficients to 0, but I'm not sure that approach makes sense for nnls models. (I quite wlling to be educated.)
