group_func_2
creates groups of variables based on community analysis.
group_func_2(absXcor, c0)
absXcor |
A numeric matrix. The absolute value of a correlation or distance matrix. |
c0 |
A numeric scalar. The thresholding |
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.
It uses the infomap.community
function of the igraph
package.
A list with one entry: the list of groups. Attributes:
"type": "normal"
"length.groups" the length of each groups.
