#3 Provide covariance matrix
It would be nice if there was a simple method to obtain the covariance matrix and perhaps parameter errors. While lm_lmdif() provides enough data to calculate the covariance matrix (I am in the process of figuring out how exactly), it does not seem completely straightforward. I guess more people would appreciate this.
