Here's what you should have done (even before posting):
?density
<Read the help page to see the structure of what density() returns.>
"Value
x the n coordinates of the points where the density is estimated.
y the estimated density values. These will be non-negative, but can
be zero."
Realize that the "specified by me" part is either going to be modified
to "pick an existing estimate near my specification" or that you will
need to approximate the value. So what is the actual problem (and the
actual data setup) ?
