mExWAS {rexposome} | R Documentation

## Class mExWAS

### Description

Class `mExWAS` obtained from mexwas method of an ExposomeSet object, contains the result of testing the multiple models of exposures of an `ExposomeSet` to a set of given phenotypes. "mExWAS" is the #' acronym of "Multivariate Exposome-Wide Association Study".

### Usage

    ## S4 method for signature 'mExWAS,ANY'
    plot(x, y, ...)

    ## S4 method for signature 'mExWAS'
    extract(object, type = "test", sort = TRUE)

    ## S4 method for signature 'mExWAS'
    plotExwas(
      object,
      ...,
      subtitles,
      color,
      exp.order,
      labels,
      show.effective = TRUE
    )

### Arguments
