R: Extract Data passed to Stan

standata.brmsfit {brms} | R Documentation

## Extract Data passed to Stan

### Description

Extract all data that was used by Stan to fit the model

### Usage

    ## S3 method for class 'brmsfit'
    standata(object, newdata = NULL, re_formula = NULL,
      incl_autocor = TRUE, new_objects = list(), internal = FALSE,
      control = list(), ...)

    standata(object, ...)

### Arguments

`object` | An object of class `brmsfit`.
`newdata` | An optional data.frame for which to evaluate predictions. If `NULL` (default), the original data of the model is used.
`re_formula` | formula containing group-level effects to be considered in the prediction. If `NULL` (default), include all group-level effects; if `NA`, include no group-level effects.
`incl_autocor` | A flag indicating if ARMA autocorrelation parameters should be included in the predictions. Defaults to `TRUE`. Setting it to `FALSE` will not affect other correlation structures such as `cor_bsts`, or `cor_fixed`.
`new_objects` | A named `list` of objects containing new data, which cannot be passed via argument `newdata`. Currently, only required for objects passed to `cor_sar` and `cor_fixed`.
`internal` | Logical, indicates if the data should be prepared for internal use in other post-processing methods.
`control` | A named list currently for internal usage only.
`...` | More arguments passed to `make_standata`.

### Value

A named list containing the data originally passed to Stan.
