extracting pairs from correlation matrix and p-value matrix
...s of the matrix and
their p-values using rcorr function in library Hmisc. Now I wish to
filter out those pairs who's PCC value is above 0.8 cut off and
p-value is less than 0.05.

column names of a correlation matrix
...atrix of 4217x4217 named 'cor_expN'. I wish
to obtain pairs with highest correlation values. So, I did this
> b=matrix(data=NA,nrow=4217,ncol=1)
> rownames(b)=rownames(cor_expN)
> for(i in 1:4217){b[i,]=max(cor_expN[i,])}
> head(b)

Now I want the corresponding columns for the above values. For that I tried
this
> c=matrix(data=NA,nrow=4217,ncol=1)
> for(i in 1:4217){b[i,]=colnames(max(cor_expN[i,]))}
And got th...
