Dear friends from the R-community, I am Guy Roger and live in Germany. I am student and user of R. I wanted to do some prediction after a linear regression fitting but could?nt because of the following message:
yx<-predict(lm(y~x4+x5),newdata=data.frame(X4,X5))
Warnmeldung: In predict.lm(lm(y ~ x4 + x5), newdata = data.frame(X4, X5)) : Vorhersage durch Fit ohne vollen Rang mag t?uschen
I cannot read the error message, but I will bet dollars to donuts that it has to do with the fact that .... x4 ist nicht X4
