Given data, return a data frame with the structure of the data

Usage

get_structure(formula = NULL, data)

Arguments

formula

Formula of the form `Yobs ~ Z | clusterID` (or `Yobs ~ Z | clusterID | blockID` if blocked). If NULL, `data` is assumed to already be in canonical form (columns `Yobs`, `Z`, `clusterID`, and optionally `blockID`).

data

Data frame holding the outcome, treatment, and clustering/blocking columns referenced by `formula` (or already in canonical form if `formula` is NULL).

Value

Dataframe listing blockID, clusterID, treatment status, and number of units in the cluster.
