Calculate body mass index

Description

Calculate body mass index

Usage

get_bmi(
  wt,
  wt_unit = c("kg", "lb", "oz", "st"),
  ht,
  ht_unit = c("cm", "m", "in", "ft"),
  target = NULL
)

get_wt_kg(wt, wt_unit = c("kg", "lb", "oz", "st"))

get_ht_m2(ht, ht_unit = c("cm", "m", "in", "ft"))

bmi_check(bmi)

target_wt(
  target,
  ht,
  ht_unit = c("cm", "m", "in", "ft"),
  wt_unit = c("kg", "lb", "oz", "st")
)

Arguments

wt	body mass
wt_unit	character. Units of body mass (or desired units if target is passed. See below.)
ht	height
ht_unit	character. Units of height
target	an optional target BMI (kg/m^2), for which the corresponding body mass will be returned
bmi	internal argument

Value

If target is NULL (default), the function returns the body mass index. If target is provided, the function will use target and ht to back-calculate a target body mass in the units defined by wt_unit (kg by default).

Examples

get_bmi(160, "lb", 180, "cm")
get_bmi(ht = 5.90, ht_unit = "ft", target = 24, wt_unit = "st")
get_bmi(wt = c(60:79, NA), ht = c(NA, 160:179))
