I have performed rCCA between transcriptomics and proteomics datasets. But in the correlation matrix i got values greater than 1. What is the meaning of correlation greater than 1. The commands I executed are pasted below.
Corr_Shrink <- rcc(Prot, Rna, ncomp = 3, method = ‘shrinkage’)
cluster=cim(Corr_Shrink, comp = 1:3,margins = c(5, 6),threshold = 0.8)
write.table(as.data.frame(cluster$mat.cor),file=“Correlation.txt”,sep="\t",quote = FALSE)
