getCovariates: getCovariates

In MOFA: Multi-Omics Factor Analysis (MOFA)

Description

This function extracts covariates from the colData in the input MultiAssayExperiment object.
Note that if you did not use MultiAssayExperiment to create your createMOFAobject, this function will not work.

Usage

getCovariates(object, covariate)

Arguments

object	a MOFAmodel object.
covariate	names of the covariate

Value

a vector containing the covariate

Examples

# Example on the CLL data
library(MultiAssayExperiment)
data("CLL_data", package = "MOFAdata")
data("CLL_covariates", package = "MOFAdata")
# Create MultiAssayExperiment object 
mae_CLL <- MultiAssayExperiment(CLL_data, colData=CLL_covariates)
MOFAobject  <- createMOFAobject(mae_CLL)
# Extract covariates from the colData of a MultiAssayExperiment
gender <- getCovariates(MOFAobject, "Gender")
diagnosis <- getCovariates(MOFAobject, "Diagnosis")
# Example on the scMT data
data("scMT_data", package = "MOFAdata")
MOFAobject  <- createMOFAobject(scMT_data)
# Extract covariates from the colData of a MultiAssayExperiment
culture <- getCovariates(MOFAobject, "culture")
# Extract covariates from the phenoData of the RNA assay
cdr <- getCovariates(MOFAobject, "cellular_detection_rate")
