Change axis length in polar.plot?

Question

I want to draw a polar graph in R.

I found plotrix, which has polar.plot, but I'm open to any other solutions.

It plots a polygon just fine, even though I have a few thousand points, so great!

My question: how can I change the start value of the radial axis? ie, how to do ylim in polar.plot ?

Answer 1

Try using ggplot2 - it has a coord_polar() command to make polar plots

Here's the official Documentation: http://docs.ggplot2.org/current/coord_polar.html

And a simple tutorial to work off of: http://learnr.wordpress.com/2010/08/16/consultants-chart-in-ggplot2/

Answer 2

我找到了polar.plot的解决方案：option radial.lim 。
