cf_func: Makes filled contour plot from function

In ContourFunctions: Create Contour Plots from Data or a Function

Makes filled contour plot from function

Description

A contour plot of the given function without sidebar by default. It calls the function 'cf_grid' to make the actual plot.

Usage

cf_func(
  fn0,
  n = 100,
  xlim = c(0, 1),
  ylim = c(0, 1),
  xylim = NULL,
  batchmax = 1,
  out.col.name = NULL,
  out.name = NULL,
  pts = NULL,
  gg = FALSE,
  ...
)

Arguments

fn0	function to plot, first argument must be two-dimensional
n	number of points in each dimension
xlim	x limits for the contour plot
ylim	y limits for the contour plot
xylim	x and y limits for the contour plot, use when both are same #@param mainminmax whether the min and max values should be shown in the title of plot
batchmax	number of datapoints that can be computed at a time
out.col.name	if a column needs to be selected from the function, specify it
out.name	Selects with a $ the name from output to be used, for lists and data frames #@param pretitle Text to be preappended to end of plot title #@param posttitle Text to be appended to end of plot title #@param title Title for the plot #@param mainminmax_minmax Whether [min,max]= should be shown in title or just the numbers
pts	Points to plot on top of contour
gg	Should ggplot2 be used? Will use gcf_grid() instead of cf_grid().
...	Passed to cf_grid

Examples

cf_func(function(x){x[1]*x[2]})
cf_func(function(x)(exp(-(x[1]-.5)^2-5*(x[2]-.5)^2)))
cf_func(function(xx){exp(-sum((xx-.5)^2/.1))}, bar=TRUE)
cf_func(function(xx){exp(-sum((xx-.5)^2/.1))}, bar=TRUE, mainminmax=TRUE)
cf_func(function(x)(exp(-(x[1]-.5)^2-5*(x[2]-.5)^2)), with_lines=TRUE)
