I am trying to run a glm regression analysis. I am getting an error
# Error in `contrasts<-`(`*tmp*`, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels
Now I have read many threads where this problem has been discussed by using
debug_contr_error(data) but I am getting another error that
# Error in debug_contr_error(data) : could not find function "debug_contr_error"
I think I am missing some package installation here. Can anyone please help. The code that I am using for glm regression (my data frame is 'data' and placed is one of the column names)
model <- glm(placed ~.,family=binomial(link='logit'),data=data)
