Set an option in the R tibble package

Question

The tibble package at version 1.4.2 has options which are listed in the documentation under tibble-options. For example, one such option is tibble.max_extra_cols which defaults to 100.

How does one access and set these options?

Answer 1

Use options to set and getOption to retrieve. For example, below we set "tibble.print_min" to 3; then we show that we did indeed set it and display the 150 row iris dataset as a tibble noting that only 3 rows display. Finally we set "tibble.print_min" back to its default noting that if getOption("tibble.print_min") returns NULL it means that the default will be used. Now 10 rows are displayed.

library(tibble)

options(tibble.print_min = 3)
getOption("tibble.print_min")
## [1] 3

as.tibble(iris)
## # A tibble: 150 x 5
##   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
##          <dbl>       <dbl>        <dbl>       <dbl> <fct>  
## 1         5.10        3.50         1.40       0.200 setosa 
## 2         4.90        3.00         1.40       0.200 setosa 
## 3         4.70        3.20         1.30       0.200 setosa 
## # ... with 147 more rows

options(tibble.print_min = NULL)
getOption("tibble.print_min")
## [1] NULL
