piecewise | R Documentation |
Compute zeros and area of a piecewise linear function.
piecewise(x, y, abs = FALSE)
x , y |
x- and y-coordinates of points defining the piecewise linear function |
abs |
logical; shall the integral or the total area between the x-axis and the function be calculated |
Compute zeros and integral resp. area of a piecewise linear function given by points with x and y as coordinates.
Returns a list with the integral or area as first element and the vector as all zeroes as second.
