Hi all, I originally posted this to the bioconductor group, but maybe it's better suited to the r-help... I'm using som() to partition samples of gene expression data into clusters. The point is to classify control vs. experimental cases (sample clustering). The original matrix was 22283 x 8. The 8 samples have 4 controls and 4 experimentals. I transposed the matrix so that its dim

Good Afternoon, I''m new to the mailing list and was wondering if anyone could help me with my current headache. I saw in the previous posts that someone else has had the problem of shifty markings. I too am finding the text immediately above what I wrote appearing in the coding reports, even though the coding in the documents themselves remains as it should. The project involves

Hello, I can get the median for each factor, but I'd like another column to go with each factor. The nm column is a long name for the lvls column. So unique work except for the order can get messed up. Example: x =

Hello, What would be the best way to design a table of posts that belong to a unknown depth of categories. Say i wanted to display the posts of data (i.e., craigslist) but the category could be something like NewYork/RealEstate/Housing/ForSale/ByOwner. Would acts_as_tree work best here and assign each sublevel to a different id? just trying to take the easiest approach here using the best

This is driving me nuts:-) I''ve brought it down to a simplified case where I''m rendering this rjs template: page.insert_html :top, ''cat1'', "<li>Some list item</li>" According to FireBug, this is what I''m actually getting in the browser: try { new Insertion.Top("cat1", "<li>Some list

Hi, I am having some difficulties with matrix operations. It is a little hard to explain it so please bear with me. I have a very large data set, large enough that it needs to be split in parts in order to deal with. I can work things on these "parts" but the problem lies in adding together these parts for the final answer. So that been said, let's say that i split the data in 2
