Hi, for those with experience of Gruff module: suppose I want to send image from server straight to the browser (as example on gruff web site): send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'', :filename => "gruff.png") the server seems sending this binary data ok, but I am having

hi, all I have two questions on using R console effectively (this is on Mac, not sure if it applies to win platform): First, I'd like to make the console font bigger, the default is too small for my screen. There is a "Show Fonts" from Format menu where you can adjust it, but it seems only for current session. Next time I start R, I have to redo everything. My question is, is there

hi, all I inherited a data set with format like the following: para.A para.B para.C observation.1 observation.2 observation.3 .... Essentially, the same experiment (with same parameters) are conducted 3 times, with corresponding observations. What are the efficient ways of re-arranging this data set in a one row per observation such that: para.A para.B para.C observation.1 para.A

Hi all, I am a grad student at Carnegie Mellon University. I had my course work in advanced storage systems in previous semester, and I am interested to work on Lustre. I prefer to take up a project that could be completed in a duration of a month or two. Since I am a novice w.r.t. my familiarity with Lustre code base, I seek your opinion to choose a project from the list:

hi, I am a R beginner. One thing I notice is that when do graphing is, if I want to draw two figures in a row such as this: par(mfrow(1, 2)) plot(...) plot(...) Each figure inside will be rectangle instead of the familiar square shape. Though you can drag the edge the window to resize it. I would have prefer this can be done automatically ... also when I do the pdf export for example. Is this
