Description Usage Arguments Value Author(s) References See Also Examples

Returns a classification tag to assign a sexual dimorphism assessment of the phenotypic change.

    classificationTag(phenTestResult, 
					userMode = "summaryOutput",
					phenotypeThreshold = 0.01,
					outputMessages=TRUE)

`phenTestResult`	instance of the `PhenTestResult` class that comes from the function `testDataset`; mandatory argument
`userMode`	flag: "vectorOuput" a sexual dimorphic classification is assigned with a proviso of later assessing the overall statistical significance; "summaryOutput" the phenotypeThreshold is used to assess the overall statistical significance and then if significant the sexual dimorphic classification determined; defaults to summaryOutput
`phenotypeThreshold`	a numerical value defining the threshold to use in classificationTag in determining whether the genotype effect is classed as significant or not; default value 0.01
`outputMessages`	flag: "FALSE" value to suppress output messages; "TRUE" value to show output messages ; default value TRUE

Returns a classification tag to assign a sexual dimorphism assessment of the phenotypic change.

If you are working interactively with the data, the argument "userMode" set to the value "summaryOutput" will use the "phenotypeThreshold" argument's value to assess statistical significance of the genotype effect and if significant then assign a sexual dimorphic classification. Alternatively, if the "userMode" set to the value "vectorMode", a sexual dimorphic classification will be returned with the MM framework where later you can globally assess whether the variable had a significant genotype effect. With the FE framework and the vectorMode, a NA is returned as the type of the effect cannot be assessed without assessing the statistical significance of the genotype effect.
