Plot observed vs. fitted values (weighted nls)
...UE)
x<-csdata$time
y<-csdata$conc
Now, I want a plot of the observed vs. fitted values. I used
# 1. 'seq' to generate series of values for x-axis
# 2. 'predict' to calculate the fitted values
# 3. 'lines' to overlay the smooth curve of the fitted values
smoothx<-seq(0,20,0.1)
smoothy<-predict(cs.wt,list(x=smoothx))
*Unfortunately, this did not work.
My goal was to use
plot(x,y)
lines(smoothx,smoothy)
Got--Error in xy.coords(x, y) : x and y lengths differ--
ANY SUGGESTIONS? PLEASE:-)
