Print data frames as tibbles.
Install with:
remotes::install_github("moodymudskipper/tibbleprint"){tibbleprint} overrides base::print.data.frame() and
base::format.data.frame().
library(tibbleprint)
#> Registered S3 methods overwritten by 'tibbleprint':
#> method from
#> format.data.frame base
#> print.data.frame baseIt’s usually bad practice to override base methods. It’s unlikely to have terrible consequences in this case though, and it’s nice to be able to benefit from {tibble}’s pretty output on regular data frames.
In any case better use it on own projects, or remove from final deliverable to avoid confusing collaborator or reader, or make your local R authority grumpy.
It’s also probably a bad idea to place the library call in your RProfile.
After the package is attached, data frames will print like tibbles, and printing of data frames will be affected by {tibble} and {pillar}’s options.
The only two differences are that the header is different and row names are displayed by default when they exist. Tibbles don’t have row names, so this adjustment was necessary.

when you want to display small objects nested inside list columns, in
