combineSGP: Combine student data and SGP results

Description

Utility function/exemplar used to merge student long data with results from studentGrowthPercentiles and/or studentGrowthProjections calculations. Default values of this function are designed to be used following use of other utility functions: prepareSGP and analyzeSGP.

Usage

combineSGP(sgp_object=sgp_object,
	years=years,
	content_areas=content_areas,
	sgp.percentiles=sgp.percentiles,
	sgp.projections.lagged=sgp.projections.lagged,
	state=state)

Arguments

sgp_object

A list containing both Student (from prepareSGP) and SGP (from analyzeSGP) slots.

years

A vector indicating what years are being analyzed.

content_areas

A vector indicating what content areas are being analyzed.

sgp.percentiles

A boolean variable indicating whether to combine student growth percentiles.

sgp.projections.lagged

A boolean variable indicating whether to combine lagged projections and calculate catch-up/keep-up values.

state

Acronym for which state is to be used for the lagged projections and growth to standard analyses.

Value

• Function returns a list containing the input long data set in the Student slot as a data.table keyed using VALID_CASE, CONTENT_AREA, YEAR, ID merged with student growth percentiles and/or lagged projection targets and catch up/keep up status.
