This method returns the number of observation that were used to fit the model, as numeric value.

## Usage

```
n_obs(x, ...)
# S3 method for glm
n_obs(x, disaggregate = FALSE, ...)
# S3 method for svyolr
n_obs(x, weighted = FALSE, ...)
# S3 method for afex_aov
n_obs(x, shape = c("long", "wide"), ...)
# S3 method for stanmvreg
n_obs(x, select = NULL, ...)
```

## Arguments

- x
A fitted model.

- ...
Currently not used.

- disaggregate
For binomial models with aggregated data,

`n_obs()`

returns the number of data rows by default. If`disaggregate = TRUE`

, the total number of trials is returned instead (determined by summing the results of`weights()`

for aggregated data, which will be either the weights input for proportion success response or the row sums of the response matrix if matrix response, see 'Examples').- weighted
For survey designs, returns the weighted sample size.

- shape
Return long or wide data? Only applicable in repeated measures designs.

- select
Optional name(s) of response variables for which to extract values. Can be used in case of regression models with multiple response variables.
