Given a correlation matrix, how can I know which variables have certain correlation values?
aa <- matrix( rnorm(25, 1,1), 5,5)
colnames(aa) <- c("v1", "v2", "v3", "v4", "v5")
aacor <- cor(aa)For instance, which variables are negatively correlated? aacor[aacor<0] # provide the r values, but how I get the variables?
Any suggestion? Thanks in advance
Juli
