Description

Plot egg count data to reflect changes between before and after treatment.

Usage

plotCounts(data, paired=TRUE, points=TRUE, points.method="jitter", 
           xlabel="", ylabel="Faecal egg counts", ...)

Arguments

data

a data frame with two columns, the first column is before treatment counts, the second column is after treatment counts.

paired

logical. If true, uses the plot for the paired design. Otherwise uses the plot for the unpaired design

points

logical. If true, add individual points for unpaired plot. Omitted if paired is TRUE.

points.method

a quoted keyword to be used to separate coincident points if points is TRUE. The default method "overplot" causes such points to be overplotted, but it is also possible to specify "jitter" to jitter the points, or "stack" have coincident points stacked.

xlabel

label of x-axis.

ylabel

label of y-axis.

...

Additional argument for function xyplot if paired is TRUE, for function boxplot otherwise.

Value

A plot is returned based on the arguments.

Details

For paired data, a xyplot is used. For unpiared data, a grouped boxplot is used.
