Description

plot.dfCorTest, a method to plot the output of dfCorTest. It is designed to give a quick overview of a dfCorTest object and to check the assumption of independece between development factors.

Usage

## S3 method for class 'dfCorTest'
plot(x, type = "l", xlab = "T", ylab = "Density", 
                          main = "Development Factor Correlation", col.area = "gray",
                          border = NA, ...)

Arguments

x	output from dfCorTest
type	Default: "l". What type of plot should be drawn
xlab	Default: "Z". X axis label
ylab	Default: "Density". Y axis label
main	Default: "Development Factor Correlation". Plot title
col.area	Default: "gray". Color of the shaded area.
border	Default: NULL, the color to draw the border. Use border = NA to omit borders.
...	optional arguments. See plot.default for more details.
