bland_altman_plot: Extended Bland-Atlman limits of agreement (LoA) plot

In MethodCompare: Bias and Precision Plots

Description

This function produces the extended Bland-Altman Limits of Agreement (LoA) plot when there are repeated measurements with possibly heteroscedastic variance of measurement errors.

Usage

bland_altman_plot(data, new = "y1", Ref = "y2", ID = "id", fill = TRUE)

Arguments

data	a dataframe contains the object identification number (id), the measurement values from the new measurement method (y1) and those from the reference standard (y2)
new	specify the variable name or location for the new measurement method
Ref	specify the variable name or location for the reference measuerment method
ID	specify the variable name for location for the subject identification number (id)
fill	logical. if TRUE use the average value for new methods to fill out the missing value (only useful for drawing a plot with all the measurements by the reference standard)

Details

This functions computes the limits of agreement (LoA) when there are repeated measurements and possibly heteroscedastic variance of measurement errors
