Access a catalog of variables

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)

Arguments

x

a Dataset

value

For the setters, a VariableCatalog to assign.

Value

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.

Details

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.
