[R] Visualize Sparse Matrix.

Hi, First of all, sorry for my question it could be so basic for a common user in R, but I am starting with this new environment. I have done a clustering job and I would like to visualize my vectors. I have a matrix of TF-IDF weights of 4602 x 1817. I store the values in a CSV file. How can

Re: [R] New installation

I have tried many Linux distributions before, and never looked back after switching for Arch Linux. It is one of the best distributions with regard to having an up to date but still reasonably stable system. Other options are Fedora Rawhide (there's a Fedora SIG mailing list) or Debian Sid (as

Perhaps r-sig-debian is more appropriate, though it is not clear to me that a debian based linux is in fact the best for running R. Of course "best" is not clearly defined here, but I highly recommend Archlinux. Best, Ista On Jun 9, 2016 6:47 PM, "Bert Gunter" wrote: > I

I suggest that you post to the r-sig-debian list instead of here. I think you are more likely to get good answers to your query there. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in
