Describe a data frame in plain text
Arguments
- x
A data frame or tibble.
- ...
Additional arguments are silently ignored.
- format
One of
"skim","glimpse","print", or"json"."skim"is the most information-dense format for describing the data. It uses and returns the same information asskimr::skim()but formatting as a JSON object that describes the dataset.To glimpse the data column-by-column, use
"glimpse". This is particularly helpful for getting a sense of data frame column names, types, and distributions, when pairings of entries in individual rows aren't particularly important.To just print out the data frame, use
print().To get a json representation of the data, use
"json". This is particularly helpful when the pairings among entries in specific rows are important to demonstrate.
- dims
The number of rows and columns to show, as a numeric vector of length two. For example, the default
dims = c(5, 100)shows the first 5 rows and 100 columns, whereasdims = c(Inf, Inf)would show all of the data.
Value
A character vector containing a representation of the data frame. Will error if the named data frame is not found in the environment.
