Hi all, I am a student of MRes Bioinformatics and Comp. Biology at University of Leeds, UK. I am trying to compare two matrices in R. One is the matrix containing distance and the other one contains the correlation values. I would like to create a XY plot of these matrices and do some linear regression on it. But, I am a bit new to R, so i have a few questions (I searched in the documentation with no success). I have been successful so far in reading both matrices but dont exactly know how can I get the plot for the same. Thanks very much.
