kernsm


Object of class <code>"array"</code> containing the original (response) data
  on a grid



Determines the kernel function. 
Object of class <code>"character"</code> kernel, can be any of
     <code>c("Gaussian","Uniform","Triangle","Epanechnicov","Biweight","Triweight")</code>.
Defaults to <code>kern="Gaussian"</code>


kern


Object of class <code>"integer"</code> vector of length <code>length(dy)</code> 
       determining the order of derivatives specified for the coordinate directios.


    number of sectors to use. Positive weights are restricted to the sector
     selected by <code>sector</code>


nsector


Object of class <code>"integer"</code> between <code>1</code> and <code>nsector</code>. sector used. 


sector


Object of class <code>"logical"</code> determines if sectors are symmetric with respect to the origin.   ~~Describe <code>symmetric</code> here~~


symmetric


Performs Kernel smoothing on a 1D, 2D or 3D grid by fft

The package contains R-functions implementing the
Propagation-Separation Approach to adaptive smoothing as
described in J. Polzehl and V. Spokoiny (2006),
Propagation-Separation Approach for Local Likelihood Estimation,
Prob. Theory and Rel. Fields, 135(3):335--362.
and J. Polzehl and V. Spokoiny (2004) Spatially adaptive
regression estimation: Propagation-separation approach,
