reverse_scale: Reverse numeric, logical, or date/time continuous variables

In joon-e/tidycomm: Data Modification and Analysis for Communication Research

Reverse numeric, logical, or date/time continuous variables

Description

Reverses a continuous scale into a new variable. A 5-1 scale thus turns into a 1-5 scale. Missing values are retained. For a given continuous variable the lower and upper end of the scale should be provided. If they are not provided, the function assumes the scale's minimum and maximum value to represent these lower/upper ends (and issues a warning about this fact). This default behavior is prone to errors, however, because a scale may not include its actual lower and upper ends which might in turn affect correct reversing. Hence, it is strongly suggested to manually set the lower and upper bounds of the original continuous scale.

Usage

reverse_scale(
  data,
  ...,
  lower_end = NULL,
  upper_end = NULL,
  name = NULL,
  overwrite = FALSE
)

Arguments

data	A tibble or a tdcmm model.
...	Numeric variables to be reverse scaled. If none are provided, all numeric columns will be scaled.
lower_end	Lower end of provided continuous scale (default is to use minimum value of current values, which might not be the actual lower end of the scale).
upper_end	Upper end of provided continuous scale (default is to use maximum value of current values, which might not be the actual upper end of the scale).
name	Optional name for the new reversed variable when a single variable is provided. By default, the name will be the original variable name suffixed with ⁠_rev⁠.
overwrite	Logical. If TRUE, it overwrites the original variable(s) with the reversed values. If FALSE (default), a new variable(s) is created.

Value

A tdcmm model with the reversed variable(s).

Examples

WoJ %>% reverse_scale(autonomy_emphasis, lower_end = 0, upper_end = 1)
WoJ %>% reverse_scale(autonomy_emphasis, name = "my_reversed_variable",
lower_end = 0, upper_end = 1)
WoJ %>% reverse_scale(overwrite = TRUE)
WoJ %>%
  reverse_scale(autonomy_emphasis, lower_end = 0, upper_end = 1) %>%
  tab_frequencies(autonomy_emphasis, autonomy_emphasis_rev)
