skim-attr {skimr}

Functions for accessing skim_df attributes

Description

These functions simplify access to attributes contained within a skim_df. While all attributes are read-only, being able to extract this information is useful for different analyses. These functions should always be preferred over calling base R's attribute functions.

Usage

data_rows(object)

data_cols(object)

df_name(object)

dt_key(object)

group_names(object)

base_skimmers(object)

skimmers_used(object)

Arguments

object

A skim_df or skim_list.

Value

Data contained within the requested skimr attribute.

Functions

• data_rows(): Get the number of rows in the skimmed data frame.

• data_cols(): Get the number of columns in the skimmed data frame.

• df_name(): Get the name of the skimmed data frame. This is only available in contexts where the name can be looked up. This is often not the case within a pipeline.

• dt_key(): Get the key of the skimmed data.table. This is only available in contexts where data is of class data.table.

• group_names(): Get the names of the groups in the original data frame. Only available if the data was grouped. Otherwise, NULL.

• base_skimmers(): Get the names of the base skimming functions used.

• skimmers_used(): Get the names of the skimming functions used, separated by data type.
