      cex.name = 2,
     var.range,
    diff.range,
     var.names = FALSE )

Arguments

data Data frame with data.
which Which variables represent the different methods. If the dataframe has a column meth, data are automatically converted to wide format and all methods compared.
col.LA What color should be used for the limits of agreement.
cex.name Character expansion factor for plotting method names
var.range The range of the axes in the scatter plot and the x-axis in the Bland-Altman plot be?
diff.range The range of yaxis in the Bland-Altman plot. Defaults to a range as the x-axis, but centered around 0.
