FindPrec {leapp}R Documentation

compute the precision 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 precision from the retrieved genes and the true positive genes.

Usage

 FindPrec(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

prec

A vector of precisions at given sizes of retrieval.
