Description Usage Arguments Value See Also Examples

Computes a 2D function values over a given area.

1	sheet(f, lims, n = 101, plot = TRUE, ...)

`f`	A list with name, other named arguments to `f`. See example below.
`lims`	a 2 x 2 array or data frame. the first row are the limits in the x axis, and the row 2 are the limits of the y axis.
`n`	a single scalar or a 2-elements array with the number of values in each direction.
`plot`	logical. Should display a plot?
`...`	further arguments passed to the function image.default.

An array of the values computed.

sheet is the 2D analog of curve.

# Example 1
ss <- function(x, y, m = 5) {m * x + y}
ex0=1; exf=4; ey0=6; eyf= 7
elims <- rbind(x = c(ex0, exf), y = c(ey0, eyf)); print(elims)
ez <- sheet(f=list(name = ss, m=10),
      lims= elims,
      n = c(exf-ex0 + 1, eyf-ey0 + 1))
print(ez)

# Example 2
ez <- sheet(f=list(name=ss), lims = elims)
