Hi R Gurus: I have a tiny data set:> xs[1] 0.7 2.8 0.1 1.9 0.0 1.4 0.2 2.3 0.3 0.2>and generate the density function for it. I would like to replicate this. Is there a straightforward way to do this, please? According to the help file, the FFT is used. How does this compare to Silverman's version from his page 15 Equation 2.2a, please? Thanks, Edna Bell
