get_rand_indices {scregclust} | R Documentation |
Compute Rand indices
Description
Compute Rand indices for fitted scregclust object
Usage
get_rand_indices(fit, groundtruth, adjusted = TRUE)
Arguments
fit |
An object of class |
groundtruth |
A known clustering of the target genes (integer vector) |
adjusted |
If TRUE, the Adjusted Rand index is computed. Otherwise the ordinary Rand index is computed. |
Value
A data.frame
containing the Rand indices. Since there can
be more than one final configuration for some penalization
parameters, Rand indices are averaged for each fixed penalization
parameter. Returned are the mean, standard deviation and number
of final configurations that were averaged.
