In mcbeem/ZPDGrowthTrajectories: Simulate achievement growth trajectories using a theoretical model of academic achievement based on the zone of proximal development

Description

Function for converting the student characteristics into a list in which the first list element is a matrix as expected by the ZPDGrowthTrajectories function called by ZPDGrowthTrajectories() function

Usage

students.to.list(
  learn.rate,
  home.env,
  decay.rate,
  initial.ach,
  which.curriculum
)

Arguments

learn.rate	vector of learning rates, one for each student
home.env	vector of home environments, one for each student
decay.rate	vector of decay rates, one for each student
initial.ach	vector of achievement values, one for each student
which.curriculum	a vector of values indicating which version of the school curriculum should be presented during interval t. The numbers index list elements of the curriculum.start.points and curriculum.widths objects

Examples

## Not run: 
# learning rate
learn.rate <- c(.08, .10, .12, .18)

# decay rate
decay.rate <- c(.04, .03, .02, .01)

# initial achievement
initial.ach <- rep(0, times=4)

# quality of home environment
home.env <- c(.06, .12, .15, .20)

students.to.list(learn.rate=learn.rate, home.env=home.env, decay.rate=decay.rate,
                initial.ach=initial.ach,
                which.curriculum=c(rep(1, times=length(learn.rate)/2),
                rep(2, times=length(learn.rate)/2)))

## End(Not run)
