Source: R/cholesterol-and-obesity.R
calculate_WHR.Rd

This function calculates the Waist-to-Height Ratio (WHR) by dividing the waist circumference by the height of the respondent.

Usage

calculate_WHR(HWM_11CM, HWM_14CX)

Arguments

HWM_11CM

A numeric value representing the height of the respondent in centimeters.

HWM_14CX

A numeric value representing the waist circumference of the respondent in centimeters.

Value

A numeric value representing the WHR:

  • If both HWM_11CM and HWM_14CX are provided, the function returns the WHR (waist circumference divided by height).

  • If either HWM_11CM or HWM_14CX is missing, the function returns a tagged NA (NA(b)) indicating an invalid input or non-response.

Examples


# Example 1: Calculate WHR for a respondent with height = 170 cm and waist circumference = 85 cm.
calculate_WHR(HWM_11CM = 170, HWM_14CX = 85)
#> [1] 0.5
# Output: 0.5 (85/170)

# Example 2: Calculate WHR for a respondent with missing height.
calculate_WHR(HWM_11CM = NA, HWM_14CX = 85)
#> [1] NA
# Output: NA(b)
