Hy Pals,
I am having problems running lineXtester analysis.
my input code is:
library(agricolae)
output2<-with(main,lineXtester(replication, female, male, vigor))
I keep getting this error code and i don't know how to handle it:
ANALYSIS LINE x TESTER: vigor
output<-with(hoe,lineXtester(replication, male, female, vigor))
ANALYSIS LINE x TESTER: vigor
Error in contrasts<-
(*tmp*
, value = contr.funs[1 + isOF[nn]]) :
contrasts can be applied only to factors with 2 or more levels
I will appreciate any advice on how to handle it urgently.
Thank you all
