##### Usage
ica.R.def(X, n.comp, tol, fun, alpha, maxit, verbose, w.init)
##### Arguments
X

data matrix

n.comp

number of components to be extracted

tol

a positive scalar giving the tolerance at which the un-mixing matrix is considered to have converged.

fun

the functional form of the $G$ function used in the approximation to negentropy.

alpha

constant in range [1,2] used in approximation to negentropy when fun == "logcosh"

maxit

maximum number of iterations to perform

verbose

a logical value indicating the level of output as the algorithm runs.

w.init

Initial value of un-mixing matrix.

##### Details

See the help on fastICA for details.

##### Value

The estimated un-mixing matrix W.
