This functions tries to get the data that was used to fit the model and returns it as data frame.

## Usage

```
get_data(x, ...)
# Default S3 method
get_data(x, source = "environment", verbose = TRUE, ...)
# S3 method for class 'glmmTMB'
get_data(
x,
effects = "all",
component = "all",
source = "environment",
verbose = TRUE,
...
)
# S3 method for class 'afex_aov'
get_data(x, shape = c("long", "wide"), ...)
# S3 method for class 'rma'
get_data(
x,
source = "environment",
verbose = TRUE,
include_interval = FALSE,
transf = NULL,
transf_args = NULL,
ci = 0.95,
...
)
```

## Arguments

- x
A fitted model.

- ...
Currently not used.

- source
String, indicating from where data should be recovered. If

`source = "environment"`

(default), data is recovered from the environment (e.g. if the data is in the workspace). This option is usually the fastest way of getting data and ensures that the original variables used for model fitting are returned. Note that always the*current*data is recovered from the environment. Hence, if the data was modified*after*model fitting (e.g., variables were recoded or rows filtered), the returned data may no longer equal the model data. If`source = "frame"`

(or`"mf"`

), the data is taken from the model frame. Any transformed variables are back-transformed, if possible. This option returns the data even if it is not available in the environment, however, in certain edge cases back-transforming to the original data may fail. If`source = "environment"`

fails to recover the data, it tries to extract the data from the model frame; if`source = "frame"`

and data cannot be extracted from the model frame, data will be recovered from the environment. Both ways only returns observations that have no missing data in the variables used for model fitting.- verbose
Toggle messages and warnings.

- effects
Should model data for fixed effects (

`"fixed"`

), random effects (`"random"`

) or both (`"all"`

) be returned? Only applies to mixed or gee models.- component
Should all predictor variables, predictor variables for the conditional model, the zero-inflated part of the model, the dispersion term or the instrumental variables be returned? Applies to models with zero-inflated and/or dispersion formula, or to models with instrumental variable (so called fixed-effects regressions). May be abbreviated. Note that the

*conditional*component is also called*count*or*mean*component, depending on the model.- shape
Return long or wide data? Only applicable in repeated measures designs.

- include_interval
For meta-analysis models, should normal-approximation confidence intervals be added for each response effect size?

- transf
For meta-analysis models, if intervals are included, a function applied to each response effect size and its interval.

- transf_args
For meta-analysis models, an optional list of arguments passed to the

`transf`

function.- ci
For meta-analysis models, the Confidence Interval (CI) level if

`include_interval = TRUE`

. Default to 0.95 (95%).

## Model components

Possible values for the `component`

argument depend on the model class.
Following are valid options:

`"all"`

: returns all model components, applies to all models, but will only have an effect for models with more than just the conditional model component.`"conditional"`

: only returns the conditional component, i.e. "fixed effects" terms from the model. Will only have an effect for models with more than just the conditional model component.`"smooth_terms"`

: returns smooth terms, only applies to GAMs (or similar models that may contain smooth terms).`"zero_inflated"`

(or`"zi"`

): returns the zero-inflation component.`"dispersion"`

: returns the dispersion model component. This is common for models with zero-inflation or that can model the dispersion parameter.`"instruments"`

: for instrumental-variable or some fixed effects regression, returns the instruments.`"location"`

: returns location parameters such as`conditional`

,`zero_inflated`

,`smooth_terms`

, or`instruments`

(everything that are fixed or random effects - depending on the`effects`

argument - but no auxiliary parameters).`"distributional"`

(or`"auxiliary"`

): components like`sigma`

,`dispersion`

,`beta`

or`precision`

(and other auxiliary parameters) are returned.
