basic plot() question
Dear all,
I try to plot a logstic regression model as follows:
Valkror<- read.table("Valkror.txt", header=T)
np.bark<- glm(Npinc~bark, family=binomial, data=Valkror)
plot.formula(np.bark$fitted.values~ Valkror$bark)
The above looks nice but I want to connect the points with a line so I try:
plot.formula(np.bark$fitted.values~ Valkror$bark, type="b")
but it gives a somewhat! unexpected figure. :(
Could someo...
