Re: [R] How to create a dissimilarity object
Thank you, but what about dissimilarity matrix objects?

[R] How to create a dissimilarity object
Hi all, I would like to use the fpc and cluster packages for clustering. However, I would like to create a custom dissimilarity object using a library in python. Has anyone attempted or know of a work-around for creating a dissimilarity object from a csv file containing pair-wise distance measures? Thanks in advance!
