I have a small database (file csv): 'District';'HouseType';'Income';'PreviousCustomer';'Outcome' 'Suburban';'Detached';'High';'No';'Nothing' 'Suburban';'Detached';'High';'Yes';'Nothing' 'Rural';'Detached';'High';'No';'Responded' ....... itd.
After instruction str() as a result I get: > str(zielone) 'data.frame': 14 obs. of 5 variables: $ X.District. : Factor w/ 3 levels "'Rural'","'Suburban'",..: 2 2 1 3 3 3 1 2 2 3 ... $ X.HouseType. : Factor w/ 3 levels "'Detached'","'Semi-detached'",..: 1 1 1 2 2 2 2 3 2 3 ... $ X.Income. : Factor w/ 2 levels "'High'","'Low'": 1 1 1 1 2 2 2 1 2 2 ... $ X.PreviousCustomer.: Factor w/ 2 levels "'No'","'Yes'": 1 2 1 1 1 2 2 1 1 1 ... $ X.Outcome. : Factor w/ 2 levels "'Nothing'","'Responded'": 1 1 2 2 2 1 2 1 2 2 ... But when I try to built a tree I get an error. What's wrong in my file? > t.zielone=rpart(zielone$X.District~.,zielone) > plot(t.zielone) Error in plot.rpart(t.zielone) : fit is not a tree, just a root -- View this message in context: http://www.nabble.com/Problem-with-create-a-tree-tp23243589p23243589.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.
