I get the following errors (with the blanks and with blanks replaced by NA and including the option rm.na = TURE): > filename = "input_heatmap.txt" > g <- as.matrix(filedata) > fg <- rainbow(nrow(g), start=0, end=.3) > gg <-

Hi! To send the authenticity token from flex back to the server, I followed this: http://blog.dt.org/index.php/2008/06/rails-2-flex-3-and-form-authenticity-tokens/ I have two controllers in my rails app. The method described in the link above works with the actions in one controller, but does not work with the other. The controller which does not work has just one action which performs a file

Hi there I recently installed an OCFS2 filesystem on our FC-SAN. Everything seemed to work fine and I could read & write the filesystem from both servers that are mounting it. After a while though, writes coming from one node do not appear on the other node and vice versa. I am not sure what's causing this, and not very experienced at debugging filesystems. If anybody has any

Hi, These patches contain support for some features that are already in Syslinux 4 but weren't working properly on the elflink branch. It's another step closer to feature parity with Syslinux 4.

Hi! I have 3 models, User, Company and Address. Basically, a User belongs to a Company and an Address has one Company (because it can be linked to other models). In a form I want to display a User, its Company and its company Address, with fields_for. The problem is when my User has a Company, that does *not* have an Address: the part containing the Address is not displayed. I see 2 ways of
