| group_func_1 {SelectBoost} | R Documentation |
Generate groups by thresholding.
Description
group_func_1 creates groups of variables based on thresholding the input matrix.
Usage
group_func_1(absXcor, c0)
Arguments
absXcor |
A numeric matrix. The absolute value of a correlation or distance matrix. |
c0 |
A numeric scalar. The thresholding |
Details
This is a function used to create a list of groups using an input matrix and a thresholding value c0. A group is made, for every column in the input matrix.
Value
A list with one entry: the list of groups. Attributes:
"type": "normal"
"length.groups" the length of each groups.
