plot.discrim {sensR}

Plot function for discrim objects

Description

This function plots the latent distributions of sensory intensity corresponding to the items or products tested in the discrimination test.

Usage

## S3 method for class 'discrim'
plot(x, main = TRUE, length = 1000, ...)

Arguments

x

The discrim object whose latent distributions are to be plotted

main

include an automatically generated title on the plot? Default is TRUE

length

the length of the vectors to be plotted. Longer vectors gives more smooth curves.

...

additional arguments to plot and lines

Value

The function produces a plot and does not return any value.

Examples

## Generate discrim objects to be plotted:
fm1 <- discrim(10, 15, method = "threeAFC")
fm2 <- discrim(10, 15, method = "triangle")
old <- par(mfrow=c(2,1)) ## Split plotting window in two
## Plot the distributions of sensory intensity for the two objects
## and increase the line width
plot(fm1, lwd=2) 
plot(fm2, lwd=2)
par(old)
