R help - Jul 2010 - densities greater than 1 for values within an (0,1) intervall

Hello,

I used the command kdensity in order to calculate the density of 
fractions/ratios (e.g. number of longterm unemployed on total 
unemployment). Thus I try to calculate the denisty of values less than 
1. However, the values of the kernel densitiy R provided (y-scale) are 
all greater than 1. Where is the problem and how may I solve it? Does R 
have problems in calculating distributions of variables within an 
intervall of 0 and 1?

Best,
Katja

There is no constraint on the magnitude of probability density values, though
the area under the curve must be equal to one. You may be thinking of cumulative
probability distributions? If so, take a look at smoothed.df() in library
(cwhmisc).
