invExWAS {rexposome} | R Documentation

## Testing the association between an exposure and a phenotype of an ExposomeSet (modelling the exposures as response)

### Description

The `invExWAS` method performs an "Exposome-Wide Association Study" (ExWAS) using the exposures in ExposomeSet and one of its phenotype. (modelling the exposures as response)

### Usage

    invExWAS(object, formula, filter, tef = TRUE, verbose = FALSE, warnings = TRUE)

### Arguments

`object` | `ExposomeSet` that will be used for the ExWAS.
`formula` | `formula` indicating the test to be done. If any exposure is included it will be used as covariate. `exwas` metho will perform the test for each exposure.
`filter` | `expression` to be used to filter the individuals included into the test.
`tef` | (default `TRUE`) If `TRUE` it computed the effective number of tests and the threhold for the effective number of tests. Usually it needs imputed data.
`verbose` | (default `FALSE`) If set o true messages along the tests are shown.
`warnings` | (default `TRUE`) If set to `FALSE` warnings will not be displayed.

### Value

An codeExWAS object with the result of the association study

### See Also

extract to obtain a table with the result of the ExWAS, plotExwas to plot the results of the association

### Examples

    data(exposome)
    w1 <- invExWAS(expo, ~BMI)
    w2 <- invExWAS(expo, ~BMI + sex)
    plotExwas(w1, w2)
