fm1Soy.lis <- nlsList(weight ~ SSlogis(Time, Asym, xmid, scal),
data = Soybean)
fm1Soy.nlme <- nlme(fm1Soy.lis)
# Dear Nikolaus, I wish future versions to have a nice
# extractor function for the following.
fm1Soy.tab = summary(fm1Soy.nlme)$tTable
... and I leave it as an easy exercise to extract the wanted from fm1Soy.tab.
Note that this is a developer list for a future version of lme(x); for nlme you
usually should contact r-help. And next time, please supply an example such as
the above to make life easier, which will increase the chances to get a response.
