Evaluate code (given as a character string) at gridded points on the (x, y) plane

Description

Evaluate code (given as a character string) at gridded points on the (x, y) plane

Usage

eval_grid(code, xmin = 0, xmax = 1, xn = 10, ymin = xmin, ymax = xmax, yn = xn)

Arguments

code	A character string containing an R expression.
xmin, xmax, xn	grid dimensions along x-axis i.e. the minimum and maximum extents on the x axis, and the number of grid points to generate along this dimension
ymin, ymax, yn	grid dimensions along y-axis i.e. the minimum and maximum extents on the y axis, and the number of grid points to generate along this dimension. Defaults to same as x-axis

Value

data.frame of (x, y) coordinates and the evaluated function at these coordinates z

Examples

eval_grid("x + y")
