and
`JADE`

.

`method` |
The ICA method to use, either "JADE" (the default) or "fastICA". |

`X` |
A data matrix with n rows representing observations (e.g genes) and p columns representing variables (e.g samples). |

`nbComp` |
The number of components to be extracted. |

`alg.type` |
If |

`fun` |
The functional form of the G function used in
the approximation to neg-entropy (see 'details' of the
help of function |

`maxit` |
The maximum number of iterations to perform. |

`tol` |
A positive scalar giving the tolerance at which the un-mixing matrix is considered to have converged. |

`...` |
Additional parameters for |
