## Arguments

- object
A

`fixest`

object. Obtained using the functions`femlm`

,`feols`

or`feglm`

.- type
A character scalar, either

`"response"`

(default),`"deviance"`

,`"pearson"`

, or`"working"`

. Note that the`"working"`

corresponds to the residuals from the weighted least square and only applies to`feglm`

models.- na.rm
Logical, default is

`TRUE`

. Whether to remove the observations with NAs from the original data set. If`FALSE`

, then the vector returned is always of the same length as the original data set.- ...
Not currently used.

## Value

It returns a numeric vector of the length the number of observations used for the estimation (if `na.rm = TRUE`

) or of the length of the original data set (if `na.rm = FALSE`

).
