Hi list, I've searched in R-help and found some related discussions but still could not understand this type of error. My own function is pretty complex, so I would not put it here, but the basic algorithm is like this: myfun<-function(k){ mydata<-...#by someway I create a data frame mymodel<-glm(y~.,family=binomial(),data=mydata) ...#some other stuff }
as I execute this function, it gives error like this Error in inherits(x, "data.frame") : object "mydata" not found So I guess glm here tries to find "mydata" in the parent environment. Why doesn't it take "mydata" inside the function? How to let glm correctly locate it? Is this (scope/environment) mentioned in R manual?
