Hi Rabby,
Before you run your regression, try this:
is.factor(Final$Cor)
If this returns TRUE, then this variable is a factor and it will be
treated as a number of levels rather than a set of numeric values.
This usually happens when a text file is read in and there is at least
one value that cannot be converted to numeric. So if you are doing
something like this:
Final<-read.csv("Final.csv")
Try this:
Final<-read.csv("Final.csv",stringsAsFactors=FALSE)
Final$Cor<-as.numeric(Final$Cor)
If there is at least one NA value in Final$Cor, that is probably what
is causing your problem.
