Bland-Altman plot limits for R

Description

Works out plot limits for the Bland-Altman plots. Depends on the blandr.statistics function in the package.

Usage

blandr.plot.limits(statistics.results, lowest_y_axis = FALSE,
  highest_y_axis = FALSE)

Arguments

statistics.results

A list of statistics generated by the blandr.statistics function: see the function's return list to see what variables are passed to this function

lowest_y_axis

(Optional) Defaults to NULL If given a continuous variable will use this as the lower boundary of the y axis. Useful if need multiple plots with equivalent y-axes.

highest_y_axis

(Optional) Defaults to NULL If given a continuous variable will use this as the upper boundary of the y axis. Useful if need multiple plots with equivalent y-axes.

Examples

# Generates two random measurements
measurement1 <- rnorm(100)
measurement2 <- rnorm(100)

# Passes data to the blandr.statistics function to generate Bland-Altman statistics
statistics.results <- blandr.statistics( measurement1 , measurement2 )

# Calls the function
blandr.plot.limits( statistics.results )
