R help - Jun 2010 - Polar coordinate

Greetings to you all.
 I have two datasets - Time and magnitude. For a particular location, the
magnitude of the parameter varies with time. I wish to obtain a polar
coordinate distribution of time (0-24h) and magnitudes so as to visualize
how magnitude varies with different times of the day (e.g., morning,
midnight hours).
I have searched for "polar coordinates in R" but could not get helpful
hints. I would be most grateful if anyone could advise me on where to start.

Thank you.

Do a better search.

 	RSiteSearch("polar")

 	Google 'polar coordinate CRAN'

 	Google 'polar coordinate rforge'

And if these are not useful, you need to say why none of the functions for 
manipulating or plotting polar coordinates served your purpose.

Hi Ogbos,
Have a look at clock24.plot in the plotrix package.
