hconfigs {repfdr}

Enumeration of all possible vectors of association status.

Description

The function generates a matrix with all possible vectors of association status (in rows), given the number of studies and number of possible association status states in each study (2 or 3).

Usage

hconfigs(n.studies, n.association.status = 3, studies.names = NULL)

Arguments

n.studies

Number of studies in the analysis.

n.association.status

either 2 for no-association\association or 3 for no-association\negative-association\positive-association.

studies.names

Optional study names to display.

Details

This matrix should be used when selecting the rows indices for the association status vectors that are in the non-null set, specified by the used in non.null.rows in the function repfdr.

Value

Matrix with rows indicating all the possible vectors of association status.

Examples

(H <- hconfigs(n.studies = 3))
# in replication analysis the non-null vectors are:
H[apply(H,1,function(y){ sum(y==1)>1 | sum(y==-1)>1 }),]
# in meta-analysis there is only one null vector (c(0,0,0)):
H[rowSums(abs(H))!=0,]
