How to reference an R package ?
Hi
Once more I have doubts about references.
I want to give a reference of the packages I've used (gss, MASS, geoR).
For the gss package I'm using
@TechReport{gss00,
Author = {Chong Gu},
Title = {The gss package},
Institution = {CRAN},
year = 2000,
month = {22 } # dec,
}
and something similar for the others, but this doesn't look

plot(augPred(wheat.list))
Am I correct?

Error messages using nonlinear regression function (nls)
Hi all,
I am trying to use nonlinear regression (nls) to analyze some seed germination data, but am having problems with error codes.
The data that I have closely matches the germination dataset included in the drc package.
Here is the head of the data
temp species start end germinated TotSeeds TotGerminated Prop
1 10 wheat 0 1 0 20 0 0.0
2 10 wheat
