But what If the formula for a variable is much more complicated, like with CKD-epi. The formula is:
egfr_crea_ckdepi = function(creatinine, age, is_female, is_male) {
if (length(creatinine) != length(age) ||
length(creatinine) != length(is_female) ||
length(creatinine) != length(is_black)) {
stop("input vector lengths must match!")
}
a = ifelse(!is_black, ifelse(!is_female, 141, 144), ifelse(!is_female(163, 166)))
b = ifel...
