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

Description

Function for defining the school curriculum function as a piecewise linear equation called by school.growth()

Usage

school(x, slope1, slope2, start, end)

Arguments

x	achievement value
slope1	the slope of the lower leg of the school curriculum
slope2	the slope of the upper leg of the school curriculum
start	the curriculum starting location
end	the curriculum ending location

Examples

## Not run: 
x <- seq(0, 1, .001)
plot(x, school(x, slope1=10, slope2=30, start=.2, end=.4), "l")
# mark start and end points
 abline(v=c(.2, .4), lty="dotted", col="red")

## End(Not run)
