exsurf
Example Surface for 3-D Plots

### Description

The exsurf data frame has 1271 rows and 3 columns. It is an example surface for use in demonstrating the functionality of 3-D plots over a regular grid. This data frame contains the following columns:

### Arguments

V1 | A vector of 31 values starting at -2 and incrementing by 0.13. These values are replicated 41 times.
V2 | A vector of 41 values starting at -2 and incrementing by 0.1. These values are replicated 31 times.
V3 | The mathematical function: cos(V1+V2)*cos(3*V1-V2) + cos(V1-V2)*sin(V1+3*V2) + 5*exp((-V1*V1 - V2*V2)/8)

Examples

    summary(exsurf)
    # wireframe(V3~V1*V2, exsurf)
    # levelplot(V3~V1*V2, exsurf)
