title: Pairwise partial correlation of a matrix, controlling by one variable
body: <p>I have a 100-column table for which I would like to run pairwise partial correlations, controlling by the 100th column's variable using the <code>pcor.test</code> function from the <code>ppcor</code> package. Is there any partial correlation function in R that I can use the returns something like <code>rcorr</code>, taking the pairwise correlations of the whole matrix but only controlling by one variable? </p>
