Datasets contain collections of variables. For some purposes, such as
editing variables' metadata, it is helpful to access these variable catalogs
more directly. Other objects, such as cubes and folders, also define
variables() methods that expose variable metadata.
variables(x)variables(x) <- value
allVariables(x)
allVariables(x) <- value
# S4 method for CubeDims
variables(x)
# S4 method for CrunchCube
variables(x)
# S4 method for CrunchDataset
variables(x)
# S4 method for CrunchDataset,VariableCatalog
variables(x) <- value
# S4 method for CrunchDataset
allVariables(x)
# S4 method for CrunchDataset,VariableCatalog
allVariables(x) <- value
# S4 method for SearchResults
variables(x)
# S4 method for VariableFolder
variables(x)
All methods return a VariableCatalog except the VariableFolder
method, which returns a subset of x containing only variable references.
Assignment functions return x with the changes made.
a Dataset
For the setters, a VariableCatalog to assign.
For datasets, variables() returns only the active variables in the dataset,
while allVariables() returns all variables, including hidden variables.
allVariables() is not defined for other objects.
