How to Get Categorical Correlation Coefficient
...-----------------------------------------------------------------------------------
I donot know why the above correlation coefficients used the same data
are different.
They are 0.015 from as.factor(corridor1), -0.497 from as,factor(corridor2).
The string variable "corridor1" is the same catergory data with the
variable corridor2.
The difference is that "A" is replaced with "0", "B" with "1", "C"
with "2", .....
Could you tell me why they are different, and which correlation
coefficient is correct?
Thank in advance,

Learning RoR (and loving it!) to develop a website. A requirement of the website is enabling users to upload photos to be made viewable (dynamically) on the website. Is this something I can develop with RoR?
Thanks,
Jeff

usually discuss commercial products.
