I have a 350 plant genotypes that have been tested for resistance against a disease in the field. i used ANOVA to see if there is differences between the genotypes reactions. Here is my code: 

mydata=read.csv("population1ohneNAs.csv", header = TRUE, sep = ";")
mydata
summary(mydata)

ANOVA worked out

myAnovaResults=aov(mydata$Tiefe~mydata$Prüfglieder, data = mydata)
summary(myAnovaResults)

when I tried to get TukeyTest results i got this error:

resultTukey=(TukeyHSD(myAnovaResults,"Prüfglieder",ordered = TRUE))
# Error in order(means) : argument 1 is not a vector

    It's easier to help you if you include a simple [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input and desired output that can be used to test and verify possible solutions. Maybe it should be `myAnovaResults=aov(Tiefe~Prüfglieder, data = mydata)` – MrFlick Mar 29 '19 at 20:06
  • Thanks a lot, i will learn how to include a reproducible example for next time. This Time it worked out as you suggested (: (: – Dima Mar 29 '19 at 21:56
