There are some examples where a gaussian curve is cannot be produced for a species with this error.
Error in nls(r ~ k exp(-1/2 (x - mu)^2/sigma^2), start = c(mu = mu, :
step factor 0.000488281 reduced below 'minFactor' of 0.000976562
It would be good to figure this out because it is often common species with good indicator values.
In the new code a started to put in some lines for set lists of species in indicator groups from a publication. The Moist6 group in there fails...
