R help - Apr 2009 - Asking help for finding the highest density region

I am using the package hdrcde to get the highest density region. I have the data
from an unknown distribution. And I used the subroutine hdr from the package to
get the highest density region. But I always got a error message. I do not know
why. Who can help?Thanks!

The codes look like this:

j is the data set,
> hdr(j)
Error in bw.SJ(x) : no solution in the specified range of bandwidths
