Informative gene set selection using F-score
Description
The function returns geneset which is informative for a particular trait/condition using F-score as the gene selection criterion.
Usage
geneslect.f(x, y, s)
Arguments
x |
x is a N by p dataframe of gene expression, where, rows represent as genes and columns as samples/subjects (with row names as gene names/ids). |
y |
y is a p by 1 numeric vector of 1 and -1, where 1/-1 indicates the class label of the samples/subjects either of two classes (e.g. stress and control). |
s |
s is a numeric constant (< N) representing the number of genes to be selected from the large gene space. |
Details
This function identifies the genes/ geneset which is informative for the particular trait/condition using F-score as a criterion.
