library("plot") ; loads library plot xmin = 0 ; grid minimum xmax = 2*pi ; grid maximum n = 100 ; number of grid points x = xmin + (xmax-xmin)/(n-1) .* (0:n-1) ; generates grid y1 = sin(x) ; computes sin(x) y2 = sin(3.*x) ; computes sin(3x) y3 = sin(6.*x) ; computes sin(6x) z1 = setmask(x~y1, "red") ; colors sin(x) red z2 = setmask(x~y2, "green") ; colors sin(x) green z3 = setmask(x~y3, "blue") ; colors sin(x) blue plot(z1, z2, z3) ; plots data sets
