Functions to Label Data Frames by Grouping Variables

Description

Functions to label data frame rows by one or multiple grouping variables.

Usage

df_label_both(data, ..., vars = NULL, label_col = "label", sep = c(", ", ":"))

df_label_value(data, ..., vars = NULL, label_col = "label", sep = ", ")

Arguments

data

a data frame

...

One or more unquoted expressions (or variable names) separated by commas. Used as grouping variables.

vars

a character vector containing the grouping variables of interest.

label_col

Value

a modified data frame with a column containing row labels.

Functions

• df_label_both(): Displays both the variable name and the factor value.

• df_label_value(): Displays only the value of a factor.

Examples

# Data preparation
df <- head(ToothGrowth)

# Labelling: Non standard evaluation
df %>%
  df_label_both(dose, supp)

# Standard evaluation
df %>%
  df_label_both(dose, supp)

# Nesting the data then label each subset by groups
ToothGrowth %>%
  df_nest_by(dose, supp) %>%
  df_label_both(supp, dose)
