collapse_row_labels: Collapse row labels into a single column

In Tplyr: A Traceability Focused Grammar of Clinical Data Summary

Collapse row labels into a single column

Description

This is a generalized post processing function that allows you to take groups of by variables and collapse them into a single column. Repeating values are split into separate rows, and for each level of nesting, a specified indentation level can be applied.

Usage

collapse_row_labels(x, ..., indent = "  ", target_col = row_label)

Arguments

x	Input data frame
...	Row labels to be collapsed
indent	Indentation string to be used, which is multiplied at each indentation level
target_col	The desired name of the output column containing collapsed row labels

Value

data.frame with row labels collapsed into a single column

Examples

x <- tibble::tribble(
~row_label1, ~row_label2, ~row_label3, ~row_label4, ~var1,
  "A",         "C",         "G",         "M",        1L,
  "A",         "C",         "G",         "N",        2L,
  "A",         "C",         "H",         "O",        3L,
  "A",         "D",         "H",         "P",        4L,
  "A",         "D",         "I",         "Q",        5L,
  "A",         "D",         "I",         "R",        6L,

  "B",         "E",         "J",         "T",        8L,
  "B",         "E",         "K",         "U",        9L,
  "B",         "F",         "K",         "V",        10L,
  "B",         "F",         "L",         "W",        11L
