getLMS_JRS {rspiro} | R Documentation |
Calculate L,M,S of JRS (Japanese Respiratory Society 2014) equations
Description
This function calculates the L,M,S using the JRS (2014) equations (Kubota et al, Respir Investig 2014). The output of this function is used in calculating the LLN and predicted spirometry parameters. Checking of the input is also performed here.
Usage
getLMS_JRS(age, height, gender = 1, param = "FEV1")
Arguments
age |
Age in years |
height |
Height in meters |
gender |
Gender (1 = male, 2 = female) or a factor with two levels (first = male). Default is 1. |
param |
A character vector, containing one of more of the following parameters (case insensitive): "FEV1", "FVC", "FEV1FVC" |
Details
This is for internal use only.
Arguments age
, height
and gender
are vectors
of equal length, or of length one, in which case the value is recycled; if the four vectors are
not of equal length, the function stops with an error.
Value
A data.frame with L, M and S, for every patient and every parameter requested
