Aggregate Binomial Data

Description

A simple function for aggregating binomial data, from a form where y contains only 0 and 1 and X could contain duplicated rows, into a format where y is the matrix of counted successes and failures and X does not contain duplicates. If X contains factor variables, the model matrix corresponding to X will be returned.

Usage

agg_binomial(formula, data, as_list = TRUE)

Arguments

`formula`	a formula object defining the aggregation.
`data`	a `data.frame` to be aggregated.
`as_list`	a logical giving if the return value should be a `list`. If `FALSE` the return value is a `data.frame`.

Value

A list (or data.frame) containing aggregated binomial data with counted successes and failures.

Examples

set.seed(12345)
data <- data.frame(y = rbinom(50, 1, 0.7),
                   a = factor(sample(c(1, 2), 50, TRUE)),
                   b = factor(sample(c(1, 2, 3), 50, TRUE)))
agg_binomial(y ~ ., data)
