Left Continuous Piecewise Constant Function with a Finite Support.

Description

Function to evaluate a left continuous piecewise constant function with a finite support.

Usage

    piece(x, breaks, values)

Arguments

x

Vector of values where the piecewise constant function should be evaluated.

breaks

Vector of sorted breakpoints of the piecewise constant function.

values

Values of the piecewise constant function. It takes the value value[i] on the interval (breaks[i], breaks[i+1]]. The function is assumed to be zero outside its range specified as (breaks[1], breaks[length(breaks)]]. The length of the vector values must be equal to length(breaks) - 1

Value

The value of the piecewise constant function.

Examples

my.breaks <- c(-2, 1.5, 4, 7)
my.values <- c(0.5, 0.9, -2)
grid <- seq(-3, 8, by = 0.25)
piece(grid, my.breaks, my.values)
