Conditional reformatting of a pre-populated string of numbers

Source: R/apply_conditional_format.R
apply_conditional_format.Rd

This function allows you to conditionally re-format a string of numbers based on a numeric value within the string itself. By selecting a "format group", which is targeting a specific number within the string, a user can establish a condition upon which a provided replacement string can be used. Either the entire replacement can be used to replace the entire string, or the replacement text can refill the "format group" while preserving the original width and alignment of the target string.

Usage

apply_conditional_format(
  string,
  format_group,
  condition,
  replacement,
  full_string = FALSE
)

Arguments

string

Target character vector where text may be replaced

format_group

An integer representing the targeted numeric field within the string, numbered from left to right

condition

An expression, using the variable name 'x' as the target variable within the condition

replacement

A string to use as the replacement value

full_string

TRUE if the full string should be replaced, FALSE if the replacement should be done within the format group

Value

A character vector

Examples


string <- c(" 0  (0.0%)", " 8  (9.3%)", "78 (90.7%)")

apply_conditional_format(string, 2, x == 0, " 0        ", full_string=TRUE)
#> [1] " 0        " " 8  (9.3%)" "78 (90.7%)"

apply_conditional_format(string, 2, x < 1, "(<1%)")
#> [1] " 0   (<1%)" " 8  (9.3%)" "78 (90.7%)"
