fechner (version 1.0-3)

print.summary.fechner: Print Method for Objects of Class summary.fechner

Description

S3 method to print objects of the class summary.fechner.

Usage

"print"(x, ...)

Arguments

x

a required object of class summary.fechner, obtained from a call to the function summary.fechner (through generic function summary).

...

further arguments to be passed to or from other methods. They are ignored in this function.

Value

If the argument x is of required type, print.summary.fechner prints the afore mentioned summary information in ‘Details’, and invisibly returns x.

Details

The print method prints the summary information about objects of the class fechner computed by summary.fechner, which are the number of stimuli pairs used for comparison, a summary of the corresponding $S$-index values, a summary of the corresponding Fechnerian distance $G$ values, the Pearson correlation, the $C$-index, and the comparison level. Specific summary information details such as individual stimuli pairs and their corresponding $S$-index and $G$ values can be accessed through assignment (see ‘Examples’).
