Re: [R] Clustering with Mahalanobis Distance

I don't have any experience with your particular problem, but the thing I notice is that mahalanobis is that by default you specify a covariance matrix, and it uses solve to calculate its inverse. If you could supply the inverse covariance matrix (and specify inverted=TRUE to mahalanobis), that mi

[R] Clustering with Mahalanobis Distance

Dear R ExpeRts, I'm having memory difficulties using mahalanobis distance to trying to cluster in R. I was wondering if anyone has done it with a matrix of 6525x17 (or something similar to that size). I have a matrix of 6525 genes and 17 samples. I have my R memory increased to the max and am
