Hi, Being a novice this is my first usage of R.
I am trying to use rpart for building a decision tree in R. And I have the following dataframe Outlook Temp Humidity Windy Class Sunny 75 70 Yes Play Sunny 80 90 Yes Don't Play Sunny 85 85 No Don't Play Sunny 72 95 No Don't Play Sunny 69 70 No Play Overcast 72 90 Yes Play Overcast 83 78 No Play Overcast 64 65 Yes Play Overcast 81 75 No Play The first line indicating the header. When I use the formula, "CART<-rpart(Class ~ Outlook + Temp + Humidity + Windy, data=dataframe)" and trying to plot the values of CART using plot(CART), I get the following error, "Error in plot.rpart(CART) : fit is not a tree, just a root". Am I missing something here? Any help would be greatly appreciated. Btw, the dataframe was obtained by reading a csv which shouldn't be an issue. -Jagdeesh -- View this message in context: http://r.789695.n4.nabble.com/Rpart-query-tp2991198p2991198.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.
