Ok. I seem to be having some real problems today :) There is a link from the main page straight to the Wx::Frame tutorial, under the NEWS section. http://wxruby.rubyforge.org/wiki/wiki.pl Sorry for wasting everyone''s time :( Robert _________________________________________________________________ Getting married?

...the frame, but I'm missing how to do that here. * points() appears to not alter xlim and ylim. Is there a convenient way to autodetermine them based on all the points? * I've hardcoded the colors. This is the sort of thing I'd rather leave to an expert. (I.e. someone who has looked at colorblindness studies and knows which colors are easiest to distinguish.) Any ideas? Cheers, Scott

Dear R-help, Can some one explain why barplot() uses changing colors in the bars by default? I should think that most of the time when people draw barplots, they want the bars to be in the same color. (At least that's what I'd expect. The first time I used barplot() in R, I was shocked to see the colors.) As an example, one example in ?layout draws a scatterplot with histograms drawn

Most of the questions asked in the nut-user mailing list seem to me to be either erudite technical discussion of new and exotic UPS units, or n00b questions of the style "I have this old UPS so I installed NUT but it didn't work". NUT is thoroughly documented with man pages and User Manual, but from my own experience it is not easy for Joe N00b to know what a working setup

Are there any R functions for creating palettes for three-way data? For example, election maps for three parties where pure red, blue, and green show 100% for the Red, Blue, and Green parties respectively, magenta shows a 50-50 Red-Blue split with 0 for the Greens, cyan a 50-50 Blue/Green split with no Red votes and so on, with grey, black or white at a 1/3,1/3,1/3 split vote. I've spent a

I have reduced the saturation of the colours so that the text will be more easily readable. The colours in the text are very easy to change, but diagrams done with xfig need more effort. I'd like t...

...e concerning maximum line lengths for readability, and I think they are closer to 65 characters. The 90-100 character lines seem to me to be harder to read, especially with the close column spacing. I think color can be useful in diagrams, but it can be distracting in running text. Also, red/green colorblindness is probably common enough to consider choosing another color for either upsd or upsmon. The CHRG and DISCHRG status flags are probably confusing for an entry-level text, and are more informational than the critical OL/OB/LB flags. Some models do not indicate CHRG or DISCHRG, and others will omit C...

Hi all, I am looking for a clever way to create the following graph using R: I got information on the shares of some subgroups over time (summing up to 1 in each year). The graph I want to create should display the development of the individual shares over time by shading rectangulars for each share in a different color. Is there a clever of doing this? Thanks for your help Stefan

Currently I''m developing a multilingual app on rails 2.2. I liked very much the idea of Xavier Defrang to provide a locale-aware accessor for the fields that needs a translation: http://defrang.com/articles/2005/12/02/playing-with-rails-i18n I modified code a little to make it work with rails 2.2: def self.localize(*attribute_names) attribute_names.each do |attribute_name|
