Generate a special gt table for previewing a dataset

Sometimes you may want to see just a small portion of your input data. We can use gt_preview() in place of gt() to get the first x rows of data and the last y rows of data (which can be set by the top_n and bottom_n arguments). It's not advised to use additional gt functions to further modify the output of gt_preview(). Furthermore, you cannot pass a gt object to gt_preview().

Usage

gt_preview(data, top_n = 5, bottom_n = 1, incl_rownums = TRUE)

Arguments

data

Input data table

obj:<data.frame>|obj:<tbl_df> // required

A data.frame object or a tibble (tbl_df).

top_n

Top n rows to display

scalar<numeric|integer> // default: 5

The top_n value will be used as the number of rows from the top of the table to display. The default, 5, will show the first five rows of the table.

bottom_n

Bottom n rows to display

scalar<numeric|integer> // default: 1

The bottom_n value will be used as the number of rows from the bottom of the table to display. The default, 1, will show the final row of the table.

incl_rownums

Display row numbers

scalar<logical> // default: TRUE

An option to include the row numbers for data in the table stub.

Value

An object of class gt_tbl.

Details

By default, the output table will include row numbers in a stub (including a range of row numbers for the omitted rows). This row numbering option can be deactivated by setting incl_rownums to FALSE.

Examples

With three columns from the gtcars dataset, let's create a gt table preview with the gt_preview() function. You'll get only the first five rows and the last row.

gtcars |>
  dplyr::select(mfr, model, year) |>
  gt_preview()
