This function allows you to calculate the SCORE2 and OP score row wise in a data frame with the required variables. It would then retrieve a data frame with two extra columns including the calculations and their classifications

Usage

SCORE2_scores(
  data,
  Risk.region,
  Age = Age,
  Gender = Gender,
  smoker = smoker,
  systolic.bp = systolic.bp,
  diabetes = diabetes,
  total.chol = total.chol,
  total.hdl = total.hdl,
  classify
)

Arguments

data

A data frame with all the variables needed for calculation: Age, Gender, smoker, systolic.bp, diabetes, total.chol, total.hdl

Risk.region

a character value to set the desired risk region calculations. Categories should include

Age

a numeric vector of age values, in years

Gender

a binary character vector of Gender values. Categories should include only 'male' or 'female'.

smoker

a binary numeric vector, 1 = yes and 0 = no

systolic.bp

a numeric vector of systolic blood pressure continuous values

diabetes

a binary numeric vector, 1 = yes and 0 = no

total.chol

a numeric vector of total cholesterol values, in mmol/L

total.hdl

a numeric vector of total high density lipoprotein total.hdl values, in mmol/L

classify

set TRUE if wish to add a column with the scores' categories

Value

data frame with two extra columns including the SCORE2/OP score calculations and their classifications
