Hi all - my first time here and am having an issue with the Predict function.
I am using a tutorial as a guide, locate here: http://www.ats.ucla.edu/STAT/R/dae/mlogit.htm My code gives this error > newdata1$predicted <- predict(mlogit,newdata=newdata1,type="response") Error in `$<-.data.frame`(`*tmp*`, "predicted", value = c(0.332822934960197, : replacement has 810 rows, data has 6 How can I resolve this problem so I can just predict values for the supplied matrix(newdata1) instead of it trying to use my full dataset? Here is the full code up to this point. library(VGAM) mlogit<- vglm(bcsse$Active~bcsse$Impinteg+bcsse$Hsgradyr, family=multinomial(), na.action=na.pass) summary(mlogit) Impinteg<-c(1,2,3,4,5,6) Hsgradyr<-c(mean(bcsse$Hsgradyr)) newdata1<-data.frame(Impinteg,Hsgradyr) newdata1$predicted <- predict(mlogit,newdata=newdata1,type="response") newdata1 I appreciate all help in advance! -- View this message in context: http://www.nabble.com/Predict-Function-tp16654037p16654037.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
