tmod (version 0.44)

makeTmod: S4 class for tmod

Description

S4 class for tmod

Usage

makeTmod(modules, modules2genes, genes2modules = NULL, genes = NULL)

Arguments

modules

A data frame with at least columns ID and Title

modules2genes

A list with module IDs as names. Each member of the list is a character vector with IDs of genes contained in that module

genes2modules

A list with gene IDs as names. Each member of the list is a character vector with IDs of modules in which that gene is contained. This object will be created automatically if the provided parameter is NULL

genes

A data frame with meta-information on genes. Must contain the column ID. If NULL, then a data frame with only one column (ID) will be created automatically.

Details

An object of class tmod contains the module annotations (tmod$MODULES), gene to module (tmod$GENES2MODULES) and module to gene (tmod$MODULES2GENES) mappings and a gene list (tmod$GENES).

tmod$MODULES and tmod$GENES are data frames, while tmod$MODULES2GENES and tmod$GENES2MODULES are lists with, respectively, module and gene identifiers as names. The data frames MODULES and GENES must contain the column "ID", and the data frame MODULES must contain additionally the column "Title".

Objects of class tmod should be constructed by calling the function makeTmod(). This function check the validity and consistency of the provided objects, and, if necessary, automatically creates the members GENES and GENES2MODULES.

See the package vignette for more on constructing custom module sets.
