partition: Separate a big 'skim_df' into smaller data frames, by type.

In skimr: Compact and Flexible Summaries of Data

Separate a big skim_df into smaller data frames, by type.

Description

The data frames produced by skim() are wide and sparse, filled with columns that are mostly NA. For that reason, it can be convenient to work with "by type" subsets of the original data frame. These smaller subsets have their NA columns removed.

Usage

partition(data)

bind(data)

yank(data, skim_type)

Arguments

data	A skim_df.
skim_type	A character scalar. The subtable to extract from a skim_df.

Details

partition() creates a list of smaller skim_df data frames. Each entry in the list is a data type from the original skim_df. The inverse of partition() is bind(), which takes the list and produces the original skim_df. While partition() keeps all of the subtables as list entries, yank() gives you a single subtable for a data type.

Value

A skim_list of skim_df's, by type.

Functions

• bind(): The inverse of a partition(). Rebuild the original skim_df.

• yank(): Extract a subtable from a skim_df with a particular type.

Examples

# Create a wide skimmed data frame (a skim_df)
skimmed <- skim(iris)

# Separate into a list of subtables by type
separate <- partition(skimmed)

# Put back together
identical(bind(separate), skimmed)
# > TRUE

# Alternatively, get the subtable of a particular type
yank(skimmed, "factor")
