Retrieve information on experimental phenotypes recorded in eSet and ExpressionSet-derived classes.
These generic functions access the phenotypic data (e.g., covariates) and meta-data (e.g., descriptions of covariates) associated with an experiment.

phenoData returns an object containing information on both
variable values and variable meta-data. varLabels returns a
character vector of measured variables. pData returns a data
frame with samples as rows, variables as columns. varMetadata
returns a data frame with variable names as rows, description tags
(e.g., unit of measurement) as columns.
