## S3 method for class 'ped'
fill(data, ..., .direction = c("down", "up", "downup",
  "updown"), keep_attributes = TRUE)

## S3 method for class 'nested_fdf'
fill(data, ..., .direction = c("down", "up"),
  keep_attributes = TRUE)

`data`	an object of class `ped`, see `as_ped`.
`...`	A selection of columns. If empty, nothing happens. You can supply bare variable names, select all variables between `x` and `z` with `x:z`, exclude `y` with `-y`. For more selection options, see the `dplyr::select()` documentation.
`.direction`	Direction in which to fill missing values. Currently either "down" (the default), "up", "downup" (i.e. first down and then up) or "updown" (first up and then down).
`keep_attributes`	conserve attributes? defaults to `TRUE`.
