In KonradZych/SIAMCAT: Statistical Inference of Associations between Microbial Communities And host phenoTypes

Description

This function adds metadata to the feature matrix to be later used as predictors

Usage

add.meta.pred(siamcat, pred.names = NULL, std.meta =
    TRUE, verbose = 1)

Arguments

siamcat	object of class siamcat-class
pred.names	vector of names of the variables within the metadata to be added to the feature matrix as predictors
std.meta	boolean, should added metadata features be standardized?, defaults to TRUE
verbose	control output: 0 for no output at all, 1 for only information about progress and success, 2 for normal level of information and 3 for full debug information, defaults to 1

Value

an object of class siamcat-class with metadata added to the features

Examples

    data(siamcat_example)
    # Add the Age of the patients as potential predictor
    siamcat_age_added <- add.meta.pred(siamcat_example, pred.names=c('age'))

    # Add Age, BMI, and Gender as potential predictors
    # Additionally, prevent standardization of the added features
    siamcat_meta_added <- add.meta.pred(siamcat_example, pred.names=c('age',
    'bmi', 'gender'), std.meta=FALSE)
