| metaprep-class {metahdep} | R Documentation |
This is a class representation for the effect size estimates and other summary information for a single gene, from a collection of gene expression studies, usually constructed in preparation for a meta-analysis.
Objects can be created using the function metahdep.format and new.
theta:vector representing the gene's effect size estimates (differential expression measures) from the multiple studies. V:matrix representing the sampling variance/covariance matrix of the gene's effect size estimates from the multiple studies. X:matrix representing the covariate (or design) matrix for the gene. Covariate information from the multiple studies is represented here. M:matrix representing the block diagonal hierarchical structure of effect size estimates from the multiple studies. max.k:integer representing the size of the largest block on the diagonal of M, i.e., the size of the largest hierarchical dependence group for the gene. row.indices:matrix with columns named Study and Row. Optionally returned by the function metahdep.format(), to see which gene (Row) in which ES.obj object (Study) produced the data recorded in each metaprep object. gene:character representing the gene name. ### ### See the metahdep package vignette for a full example ### data(HGU.prep.list) HGU.prep.list[[7]]
