My data looks like:
A,B,C,D,Class
1,2,0,2,cl1
1,5,1,9,cl1
3,2,1,2,cl2
7,2,1,2,cl2
2,2,1,2,cl2
1,2,1,5,cl2
0,2,1,2,cl2
4,2,1,2,cl2
3,5,1,2,cl2
3,2,12,3,cl2
3,2,4,2,cl2
**The steps followed are:
trainfile <- read.csv("TrainFile",head=TRUE)
datatrain <- subset(trainfile,select=c(-Class))
classtrain <- (subset(trainfile,select=Class))
rf <- randomForest(datatrain, classtrain)
Error in randomForest.default(classtrain, datatrain) :
length of response must be the same as predictors
In addition: Warning message:
In randomForest.default(classtrain, datatrain) :
The response has five or fewer unique values. Are you sure you want to do
regression?
Could someone suggest me where I am going wrong.
Thanks
