Invert indicator values

Source: R/normalization.R
invert_indicator.Rd

Reverses the scale of an indicator (e.g., for indicators where low = good).

Usage

invert_indicator(
  data,
  indicators,
  scale = 100,
  suffix = "_inv",
  keep_original = FALSE
)

Arguments

data

Data containing the indicator

indicators

Character vector of indicator names to invert

scale

Numeric. The scale maximum. Default 100 (assumes 0-100 scale).

suffix

Character. Suffix for inverted columns. Default "_inv".

keep_original

Logical. Keep original columns? Default FALSE.

Value

Data with inverted indicator columns

Details

Some indicators have inverse relationships with "goodness":

  • Accessibility: High = more human pressure (bad for wilderness)

  • Fragmentation: High = more fragmented (bad for biodiversity)

This function inverts the scale: inverted = scale - original

Examples

if (FALSE) { # \dontrun{
# Invert accessibility for wilderness index
data <- invert_indicator(
  data,
  indicators = "accessibility_norm",
  suffix = "_wilderness"
)
} # }
