RssBioGro(obs, sim)
Computes residual sum of squares for the
BioGro function. Very simple function to
compare the distance between simulated and observed data
for the BioGro function Need to add an argument such as
pc.sigmas "plant component sigmas" If variability of the
plant component is known
## A simple example data(annualDB) data(EngWea94i) res <- BioGro(EngWea94i) RssBioGro(annualDB,res)[1] 346.0124
