dgirtin-class: A class for data ready to model

In jamesdunham/dgirt: Dynamic Estimation of Group-Level Opinion

Description

shape() generates objects of class dgirtIn for modeling with dgirt() and dgmrp().

Usage

summary(object, ...)

## S4 method for signature 'dgirtIn'
summary(object, ...)

print(x, ...)

## S4 method for signature 'dgirtIn'
print(x, ...)

get_item_names(x)

## S4 method for signature 'dgirtIn'
get_item_names(x)

get_n(x, by = NULL, aggregate_name = NULL)

## S4 method for signature 'dgirtIn'
get_n(x, by = NULL, aggregate_name = NULL)

get_item_n(x, by = NULL, aggregate_data = FALSE)

## S4 method for signature 'dgirtIn'
get_item_n(x, by = NULL, aggregate_data = FALSE)

## S4 method for signature 'dgirtIn'
show(object)

Arguments

object	An object of class dgirtIn as returned by shape.
...	Unused.
x	An object of class dgirtIn as returned by shape.
by	The name of a grouping variable.
aggregate_name	If specified get_n will operate on the table passed to shape as aggregate_data instead of on the individual data and count nonmissingness in the given variable.
aggregate_data	If specified get_item_n will operate on the table passed to shape as aggregate_data instead of on the individual data.

Value

A list of item names.

Examples

data(toy_dgirt_in)
get_item_names(toy_dgirt_in)
get_n(toy_dgirt_in)
get_n(toy_dgirt_in, by = "year")
get_n(toy_dgirt_in, by = "source")
get_item_n(toy_dgirt_in)
get_item_n(toy_dgirt_in, by = "year")
data(toy_dgirt_in)
get_item_names(toy_dgirt_in)
# respondent count
data(toy_dgirt_in)
get_n(toy_dgirt_in)

# respondent count by year
get_n(toy_dgirt_in, by = "year")

# respondent count by year and survey identifier
get_n(toy_dgirt_in, by = c("year", "source"))

data(toy_dgirt_in)
get_item_n(toy_dgirt_in)
get_item_n(toy_dgirt_in, by = "year")
