Hello Guys, thank you all very much for the help!
Sorry for my total lack of knowledge in R... so I did the correlation.. and
got these results:
> cor(A, C, method = "spearman")
>[1] 0.4922165
> cor(B, C, method = "spearman")
>[1] 0.1922412
> cor(A, B, method = "spearman")
> [1] -0.00889328
I don't know how to interpret them... so the correlation is good when it is
really close to 1 or to 0? What about negative correlation??
Cheers,
