Hi All, I need to calculate the median for even number of data points.However instead of calculating the arithmetic mean of the two middle values,I need to calculate their geometric mean. Though I can code this in R, possibly in a few lines, but wondering if there is already some built in function. Can somebody give a hint? Thanks in advance [[alternative HTML version deleted]]

This reminds me of a bug in the old Windows 98 SE desktop. What would cause this? This has happened to me once before on Fedora 3 (I think, maybe 2). -------------- next part

Hey guys, We''ve been talking about the multi-byte patch and I think it''s time to get feedback from you guys on a possible way forward. We can include ActiveSupport::Multibyte with rails 1.2, and update all of the relevant helpers to use the String#chars proxy. This will mean that none of the action view helpers will mangle multibyte strings. Similarly, if any Strings are being

Hello all, I was trying to make a volcano plot with some real data, using log2(ratio) vs. Z-value significance. However the scatter of the points is too less contrary to 'normal' volcano plots and I'm getting a sharp 'V' shaped plot. *Am I doing something wrong here?* The data(ratio) is available from pastebin: http://pastebin.com/m2Jss3qF data <-
