unexpected input in rpart
...e a set of birds of known sex and several
morphological measurements and we want to predict the sex using the
morphology. I read my csv file and it shows up in R no problem, looks fine
but when I execute the following rpart command
hawkadults_rpart<-rpart(Sex?Footpad+Mean_2ndlength+Bill_length+Tarsus_reg+Mass+Wing_chord,method="class",data=hawkadultsDF)
I get the message Error: unexpected input in "hawkadults_rpart<-rpart(Sex?"
I feel like as a newbee I'm missing something rather obvious. Any and all
help would be greatly appreciated.
Thanks
