R Documentation
compute the true positive rate at given sizes of retrieved genes
Description
Given a vector of sizes of retrieved genes, for each size k, select
the top k genes with smallest p values and compute the true positive rate from
the retrieved genes and the true positive genes.
Usage
FindTpr(pvalue, ind,topk)
Arguments
pvalue
A vector of p values, one for each gene, with length m
ind
A vector of indices that the corresponding gene are true positive
topk
A vector of integers ranging from 1 to m , length of retrieved
gene list
Value
tpr
A vector of True positive rates at given sizes of retrieval.
