Visualizing the result of nparcomp

Description

This function takes an object of class "nparcomp" and creates a plot of the confidence intervals for the estimated nonparametric contrast effects.

Usage

1
2
## S3 method for class 'nparcomp'
plot(x,...)

Arguments

x

An object of class "nparcomp", i.e. the result when applying nparcomp to a dataset. Otherwise an error will occur.

...

Arguments to be passed to methods.

Details

It is not possible to change any parameter set in the nparcomp-statement.

Since plot.nparcomp is a S3 method it suffices to use plot(x) as long as x is of class "nparcomp". It will be interpreted as plot.nparcomp(x).

Value

plot.nparcomp returns a graph that contains a confidence interval for the estimated nonparametric contrast effect of each contrast. It just visualizes the result of the nparcomp-statement.

Note

It is possible to create a graphical result directly by setting plot.simci=TRUE in the nparcomp-statement.
