R help - Jun 2008 - Accessing Max/Min Value of Density Function

Dear all,

Currently I have the following output
> mydensity <- density(x)
> print(mydensity)
       x                 y
 Min.   : -92.14   Min.   :0.000e+00
 1st Qu.: 356.66   1st Qu.:5.530e-09
 Median : 805.45   Median :4.681e-05
 Mean   : 805.45   Mean   :5.564e-04
 3rd Qu.:1254.24   3rd Qu.:3.370e-04
 Max.   :1703.04   Max.   :5.541e-03


How can I access the Max value of "x" or "y"?
I tried this, but doesn't seem to work.
> print(mydensity$y.max)
NULL

I expect it to give "5.541e-03" as output.

Please advice.

Have a look at str(mydensity)

Try max(mydensity$x), max(mydensity$y), quantile(mydensity$x), etc.

See ?density
