Re: [R] plot polar coordinates

Hi, How do we limit the Theta range plotted? In the current format, R plots the whole 2Pi range, however I want a plot between 0 and pi/2. I do not see any parameter in polar.plot to do the same, am I missing something very obvious? Regards, Avaneesh T -- View this message in context: http:/

Re: [R] plot polar coordinates

Thank you Jim, I had a liitle off-list conversation with Greg and finally I got the solution. All the code is now on http://commons.wikimedia.org/wiki/File:Sonnenstand.png I got the workaround with my own "(sun)lines" function which does the shift from cartesian coordiantes to polar coordinates. A

Re: [R] plot polar coordinates

It looks like polar.plot does not handle negative lengths, you can preprocess the data and just add 180 degrees to the angles corresponding to negative lengths and then use their absolute values. The radial.lim is not ignored, based on the documentation the range is then made pretty (and 100 is
