I want to use randomForest to classify a matrix which is 331030×42,the last column is class signal.I use :
Memebers.rf<-randomForest(class~.,data=Memebers,proximity=TRUE,mtry=6,ntree=200) which told me" the error is matrix(0,n,n) set too elements"
then I use:
Memebers.rf<-randomForest(class~.,data=Memebers,importance=TRUE,proximity=TRUE) which told me"the error is na.fail.default(list(class = c(17L, 17L, 17L, 29L, 29L, 29L,  : 
  missing values in object

what's wrong with it .Thanks a lot
