rd_3_plots_triangular {barsurf} | R Documentation |
Plots (in 2D and 3D) of functions over triangular domains.
plot2d.tricontour (x, y, z, zb, contours=TRUE, heat.map=TRUE, main, xlab="x", ylab="y", colv.1, colv.2, contrast=0, pty="s", ...) plot3d.trisurface (x, y, z, main, xlab="x", ylab="y", colv.1, colv.2, contrast=0, zlim, ...) lr2na (z)
x |
An optional sorted vector of x values. |
y |
An optional sorted vector of y values. |
z |
A square matrix of point values. |
zb |
A vector of contour values. |
contours |
If true (the default), plot contour lines. |
heat.map |
If true (the default), plot a heat map. |

colv.1 |
An HCL color vector. |
colv.2 |
An HCL color vector. |
contrast |
A numeric scalar, giving the relative contrast, currently in the interval [-1, 0]. |

Only the upper left part of the matrix is used.
Refer to the details sections of plot2d.contour() and plot3d.surface() for more information.
Note that in plot3d.trisurface(), the x and y arguments are ignored.
x = y = 1:30 f = function (x, y) x ^ 2 + y ^ 2 z = outer (x, y, f) plot3d.surface (,,z)
