Dear all, I have written a small set of functions for drawing graphical representations of R objects and evaluations of R expressions. It is mainly intended for pedagogical purposes. Here are some samples: http://panini.u-paris10.fr/~sloiseau/sampleGraphics.pdf The idea is to use some graphical conventions in order to make clear the abstract syntax and to explain function, extraction, recycling, type conversion, properties of data structures, etc. I would be very interested in your reactions and comments. I'm wondering if it may become a R pa...

...le line graphs? Given this sample code below, how would I easily modify the height/width or make it a widegraph as in the example above? Thanks for any help. data = [1, 2, 3, 4, 5, 6] g = Gruff::Line.new(500) #Sets scale to 500px, but I''d like 500 width and 300 height g.title = "Samplegraph" g.labels = {1 => "Today", 3 => "Yesterday", 6 => "The Day Before"} g.theme_37signals g.data("Graph", data, ''#378CDF'') g.maximum_value = 10 send_data(g.to_blob, :disposition => ''inline'', :type => '...
