One of the main features of the tbl_df class is the printing:

Tibbles only print as many rows and columns as fit on one screen, supplemented by a summary of the remaining rows and columns.
Tibble reveals the type of each column, which keeps the user informed about whether a variable is, e.g., <chr> or <fct> (character versus factor).

Printing can be tweaked for a one-off call by calling print() explicitly and setting arguments like n and width. More persistent control is available by setting the options described below.

## S3 method for class 'tbl'
print(x, ..., n = NULL, width = NULL, n_extra = NULL)

## S3 method for class 'tbl'
format(x, ..., n = NULL, width = NULL, n_extra = NULL)

trunc_mat(x, n = NULL, width = NULL, n_extra = NULL)

`x`	Object to format or print.
`...`	Other arguments passed on to individual methods.
`n`	Number of rows to show. If `NULL`, the default, will print all rows if less than option `tibble.print_max`. Otherwise, will print `tibble.print_min` rows.
`width`	Width of text output to generate. This defaults to `NULL`, which means use `getOption("tibble.width")` or (if also `NULL`) `getOption("width")`; the latter displays only the columns that fit on one screen. You can also set `options(tibble.width = Inf)` to override this default and always print all columns.
`n_extra`	Number of extra columns to print abbreviated information for, if the width is too small for the entire tibble. If `NULL`, the default, will print information about at most `tibble.max_extra_cols` extra columns.

Options used by the tibble and pillar packages to format and print tbl_df objects. Used by the formatting workhorse trunc_mat() and, therefore, indirectly, by print.tbl().

tibble.print_max: Row number threshold: Maximum number of rows printed. Set to Inf to always print all rows. Default: 20.
tibble.print_min: Number of rows printed if row number threshold is exceeded. Default: 10.
tibble.width: Output width. Default: NULL (use width option).
tibble.max_extra_cols: Number of extra columns printed in reduced form. Default: 100.

pillar.bold: Use bold font, e.g. for column headers? This currently defaults to FALSE, because many terminal fonts have poor support for bold fonts.
pillar.subtle: Use subtle style, e.g. for row numbers and data types? Default: TRUE.
pillar.subtle_num: Use subtle style for insignificant digits? Default: FALSE, is also affected by the pillar.subtle option.
pillar.neg: Highlight negative numbers? Default: TRUE.
pillar.sigfig: The number of significant digits that will be printed and highlighted, default: 3. Set the pillar.subtle option to FALSE to turn off highlighting of significant digits.
pillar.min_title_chars: The minimum number of characters for the column title, default: 15. Column titles may be truncated up to that width to save horizontal space. Set to Inf to turn off truncation of column titles.

print(as_tibble(mtcars), n = 1)
print(as_tibble(mtcars), n = 3)

print(as_tibble(iris), n = 100)

print(mtcars, width = 10)

mtcars2 <- as_tibble(cbind(mtcars, mtcars), .name_repair = "unique")
print(mtcars2, n = 25, n_extra = 3)

trunc_mat(mtcars)

  print(nycflights13::flights, n_extra = 2)
  print(nycflights13::flights, width = Inf)
