Quick summary functions for tibbles and data frames

At this time, the package is no longer actively maintained. I would suggest migrating to a combination of the packages janitor, skimr, and ggstatsplot for better, more comprehensive functionality.

You want to have a quick first overview of a dataset: (1) run summary functions for all (or selected) continuous and discrete variables, and (2) make histograms of all (or selected) continuous data. This package enables you to do that with the smallest amount of effort/code in R, using the power of the tidyverse.

These are a few simple functions combining the power of dplyr, purrr, and broom to quickly create summary statistics for multiple variables of a tibble or data frame, using the standard selectors in dplyr (including contains("mysubstring") and starts_with("myprefix"), for example).

• summarise_numeric summarises continous data. For grouped tibbles, summary statistics are calculated for each group seperately. You can select specific variables (like in dplyr::select), or select no specific variables at all, in which case all numeric variables are analyzed.

• summarise_date summarises Date objects. For grouped tibbles, summary statistics are calculated for each group seperately. You can select specific variables (like in dplyr::select), or select no specific variables at all, in which case all Date variables are analyzed.

• countfreq is an extension to dplyr::count. It counts observations by group, adding an extra column with (rounded) frequencies within the lowest grouping level.

• summarise_na counts missing observations (NA's) for all variables in a tibble, and the report includes (rounded) frequencies. You can select specific variables (like in dplyr::select), or select no specific variables at all, in which case all numeric variables are analyzed.

• multihistogram_numeric is a quick way to create histograms for multiple numeric variables in a tibble. You can select specific variables (like in dplyr::select), or select no specific variables at all, in which case all numeric variables are analyzed. It uses ggplot's facets to create a quick grid of multiple histograms.

• multihistogram_date is a quick way to create histograms for multiple Date variables in a tibble. You can select specific variables (like in dplyr::select), or select no specific variables at all, in which case all Date variables are analyzed. It uses ggplot's facets to create a quick grid of multiple histograms.

How to install

Tibblesummary is not (yet) available on CRAN. Install devtools. Then use devtools to install tibblesummary directly from GitHub.

install.packages("devtools")
devtools::install_github("ls31/tibblesummary")

How to update

devtools::install_github("lc31/tibblesummary")
