Hi all, I'm a newbee using R. I need to do a classification tree using the rpart package. Basically I have 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.
