I am trying to find a way to perform pairwise correlations against one gene in a matrix rather than computing every pairwise correlation. I am interested in how 1 transcription factor correlates to every gene in a matrix of 55 experiments (columns) by 23,000 genes (rows), performing the correlation by rows. Trying to perform every pairwise correlation in this fashion is too memory intensive for any computer I am currently using so I am wondering if anyone had a method for doing pairwise correlations to a single gene or if there is a preexisting package in R that might address this.
