k_centroids {GSgalgoR} | R Documentation |
This function calculates the mean value for each feature of each class to calculate the prototypic centroids of the different groups
k_centroids(data, class)
data |
a scaled gene expression |
class |
a vector with the samples classes |
returns a data.frame
with the estimated prototypic centroids
for each class with the features names as rownames
