Description

Train G-1 SVM models in k-fold cross validation scheme to select initial genes list.

Usage

intGenes(dat, grp, nfolds.out = 2, top.per = 0.05)

Arguments

dat

Original gene expression data matrix with G rows (number of genes) and S column (number of samples).

grp

Class labels.

nfolds.out

Outer cross validation number (default is 2).

top.per

All genes are ranked based on their models performance and top.per% of them are selected as initial genes.

Value

Selected initial genes.

Examples

data(malanidata)
int <- intGenes(dat,grp)
print(int$top.genes)
