Description Usage Arguments Value Author(s) Examples

A function to set classes (e.g. as numeric or factor) to the variables in the dataframe.

1	phenoDataFrame(PhenoData, variableClass)

`PhenoData`	is the dataframe of phenotypic information extracted from an `object` of class `aclinicalProteomicsData`.
`variableClass`	a character vector of length equal to the number of columns of the dataframe of phenotypic information, giving classes of the variables studied.

A dataframe of class-corrected phenotypic variables.
