get_variance_explained {MOFA2} | R Documentation

## Get variance explained values

### Description

Extract the latent factors from the model.

### Usage

    get_variance_explained(
      object,
      groups = "all",
      views = "all",
      factors = "all",
      as.data.frame = FALSE
    )

### Arguments

`object` | a trained `MOFA` object.
`groups` | character vector with the group name(s), or numeric vector with the group index(es). Default is "all".
`views` | character vector with the view name(s), or numeric vector with the view index(es). Default is "all".
`factors` | character vector with the factor name(s), or numeric vector with the factor index(es). Default is "all".
`as.data.frame` | logical indicating whether to return a long data frame instead of a matrix. Default is `FALSE`.

### Value

A list of data matrices with variance explained per group or a `data.frame` (if `as.data.frame` is TRUE)

### Examples

    # Using an existing trained model
    file <- system.file("extdata", "model.hdf5", package = "MOFA2")
    model <- load_model(file)

    # Fetch variance explained values (in matrix format)
    r2 <- get_variance_explained(model)

    # Fetch variance explained values (in data.frame format)
    r2 <- get_variance_explained(model, as.data.frame = TRUE)
