HELLO WELCOME TO R
here is your code: I'm new using R im trying to do a tukey test, but when i see the results the p value results in NA im guessing its because i have missing values but im not sure how to fix it AnovaModel.2 <- aov() If your original data.frame or your raw data have "NA's" you must to write this part AnovaModel.2 <- aov(area ~ trat, na.action=na.omit, , data=apilados) I hope that work in this way suerte!!!
