AIPcalc {LDLcalc}

Calculation of Atherogenic Index of Plasma (AIP)

Description

Calculates the Atherogenic Index of Plasma (AIP) from triglyceride and HDL values.

Usage

AIPcalc(TG, HDL, SI ,roundDigit)

Arguments

TG

A vector or data frame column containing the triglyceride (TG) values to be used for the calculation of the atherogenic index of plasma (AIP). TG and HDL must be of the same length.

HDL

A vector or data frame column containing the high density lipoprotein (HDL) values to be used for the calculation of the atherogenic index of plasma (AIP). TG and HDL must be of the same length.

SI

Boolean (default=TRUE). AIP is by definition calculated using SI units for TG and HDL (mmol/L). If mg/dl units are provided instead, SI must be set to FALSE.

roundDigit

Decimal digits to round the result to (default = 4).

Value

A vector of AIP values of length equal to the length of TG and HDL.
