Dear all, Can anyone help me? I'm having some programming command problems with R. I applied R in my task to cluster a group of 839 protein spot data. The data obtained from 6 different cell lines. Unfortunately, the dendogram doesn't clearly stated the clusters due to abundance of data. I hope to partition out the group of protein data consisting 839 data with similar characteristics first before I carry out cluster analysis. I had already tried out several methods but I still didn't manage to get a solution. Could anyone help me to solve my problem by providing me the programming command and alternative approach?? I'm running out of ideas.. Thank you. _________________________________________________________________ [[alternative HTML version deleted]]
