Retrieve information on features recorded in eSet-derived classes.
These generic functions access feature data (experiment specific information about features) and feature meta-data (e.g., descriptions of feature covariates).
featureData(object) featureData(object) <- value fData(object) fData(object) <- value fvarLabels(object) fvarLabels(object) <- value fvarMetadata(object) fvarMetadata(object) <- value
object |
Object, possibly derived from |
value |
Value to be assigned to corresponding object. |
featureData returns an object containing information on both
variable values and variable meta-data. fvarLabels returns a
character vector of measured variable names. fData returns a data
frame with features as rows, variables as columns. fvarMetadata
returns a data frame with variable names as rows, description tags
(e.g., unit of measurement) as columns.
