bwchoice

A matrix with $n$ rows (individuals) and $p$ columns (numeric variables).

A numeric vector of either length 1 or length equal to the
  number of columns of <code>X</code>. It indicates the  desired effective degree of
  freedom (trace) of the smoothing   matrix for
    each variable. <code>objectif</code> is repeated when the length of vector
  <code>objectif</code> is 1.

objectif

String which allows to choose between gaussian kernel
  (<code>"g"</code>), Epanechnikov (<code>"e"</code>), uniform (<code>"u"</code>),
  quartic (<code>"q"</code>).

kernelx

A scalar which controls the number of iterations for
    that search.

itermax


Perform a search for the bandwidths in the given grid. For each explanatory
variable, the bandwidth is chosen such that the trace of the smoothing
matrix according to that variable (effective degree of freedom) is equal to a
prescribed value.
This function is not intended to be used directly.

smooth

Multivariate smoothing using iterative bias reduction with kernel, thin plate splines, Duchon splines or low rank splines.
