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 class 'CubeDims'
variables(x)
# S4 method for class 'CrunchCube'
variables(x)
# S4 method for class 'CrunchDataset'
variables(x)
# S4 method for class 'CrunchDataset,VariableCatalog'
variables(x) <- value
# S4 method for class 'CrunchDataset'
allVariables(x)
# S4 method for class 'CrunchDataset,VariableCatalog'
allVariables(x) <- value
# S4 method for class 'SearchResults'
variables(x)
# S4 method for class '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.
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.
