tabBookWeightSpec: Helper function for setting complex weights on a 'tabbook'

In Crunch-io/crunchtabs: Custom Report Generation for Crunch Datasets

Helper function for setting complex weights on a 'tabbook'

Description

For json ['tabBook()'], you can specify a weight per variable in the dataset, where each row in the data.frame indicates a weight and alias to use for each page.

Usage

tabBookWeightSpec(dataset, weights, append_default_wt = TRUE)

Arguments

dataset	A 'CrunchDataset'
weights	A list where each item has a name that indicates the weight's alias that should be use (no name indicates unweighted) and each item is a vector of variable aliases to include as pages in the 'tabbook'.
append_default_wt	Whether to append the dataset's default weight (or unweighted pages if no weight is set) for all variables.

Value

A data.frame with two columns, 'weight', the alias of the weight to use, and alias, the alias of the variable to use the weight on. If 'append_default_wt' is 'TRUE', the returned object is sorted in the order of aliases in the dataset, and with the default weight first, followed by the weights specified in the 'weights' argument.

Examples

## Not run: 
ds <- newExampleDataset("pets")
mt <- newMultitable(~q1, ds)

weight_spec <- tabBookWeightSpec(
  ds,
  list(wt1 = "gender", wt2 = "starttime", "gender")
)

# Now can use the weight spec in `tabBook()`
tabbook <- tabBook(mt, ds, weight = weight_spec)

## End(Not run)
