Analysis and graphics by groups
...I'm trying to do analysis and graphics using a factor as a criteria to split
data and do the analysis/graphics for each subset of data.
Right now what I'm trying to do is to fit and plot the following logistic
model, according to a third variable named "Cerca":
dm_fit_T<-nls(nDMTRBgm2~(K/(1+((K-nDMTRBgm2.T.1)/nDMTRBgm2.T.1)*exp(-r))),perieph,start=list(K=3,r=0.2),trace=T)
I've found a function called gapply which seems to be what I need, but it
doesn't seem to work. This is the argument I've used:
gapply(perieph,FUN=nls(nDMTRBgm2~(K/(1+((K-nDMTRBgm2.T.1)/nDMTRBgm2.T...
