R help - Jul 2009 - Density value over 1 using density function

Dear R users,
 
Thanks in advance.



I am using R 2.9.1 on Windows XP.
 
In the plot, the density value displays over 1. How can I explain it?
 
library(urca)
plot(density(Raotbl1[, 1]))
 

Once again, thank you very much for the time you have given.
 
I am looking forward for your reply.
 
Regards,
 
Deb

It's a probability density, not a probability function.  The vertical range
doesn't have to be
restricted between 0 and 1.  In fact, if the horizontal range is narrow
enough then the
maximum must be > 1, in order for the area under the curve to equal 1.
