weight(x)

weight(x) <- value

# S4 method for class 'Analysis,CrunchVariable'
weight(x) <- value

# S4 method for class 'Analysis,NULL'
weight(x) <- value

# S4 method for class 'CrunchDataset'
weight(x)

# S4 method for class 'CrunchDataset,ANY'
weight(x) <- value

is.weight(x)

# S4 method for class 'NumericVariable'
is.weight(x) <- value
