dt2_format_number_abbrev: Abbreviate large numbers with fixed decimals (k / M / B)

In DT2: 'DataTables' 2.x for R

Abbreviate large numbers with fixed decimals (k / M / B)

Description

Adds a columns.render function that displays numbers as 1.2k, 3.4M, etc. This renderer lets you control the number of decimal places via digits. Use this when you want a fixed, compact style independent of locale rules.

Usage

dt2_format_number_abbrev(
  options = list(),
  col_specs,
  digits = 1,
  locale = NULL
)

Arguments

options	A DataTables options list to be modified.
col_specs	Column names or 1-based indices to format.
digits	Integer, decimal places for the abbreviated display (default 1).
locale	Optional BCP-47 locale string (e.g. "pt-BR"). If provided, the non-abbreviated part uses toLocaleString(locale) for grouping.

Value

The modified options list.

Examples

opts <- list(columns = names(mtcars))
opts <- dt2_format_number_abbrev(opts, c("hp","qsec"), digits = 1, locale = "pt-BR")
