filled_contour: Plot Filled Contours

In jonasbhend/myhelpers: Set of Tools for Often Performed Tasks

Description

Contrary to filled.contour, this function provides the atmoic function for contour shading in analogy with image and contour.

Usage

filled_contour(x = seq(0, 1, length.out = nrow(z)), y = seq(0, 1, length.out
  = ncol(z)), z, levels = pretty(zlim, 12), col = NULL, xlim = range(x),
  ylim = range(y), zlim = range(z[is.finite(z)]), add = FALSE,
  axes = TRUE, type = c("contour", "image"), col.axis = 1, col.box = 1,
  add.boundary = TRUE, col.contour = "grey", lty.contour = 1,
  lwd.contour = 1, drawlabels = FALSE, ...)

Arguments

x, y	Locations of grid cells for values of z.
z	Matrix containing the values to be plotted.
levels	Numeric vector of levels at which to draw contours.
col	Vector of colours to use for shading in between contours.
xlim, ylim, zlim	x- y- and z-limits for the plot.
add	Logical, hsould plot be added to existing plot?
axes	Logical, should axes and bounding box be drawn?
type	One of 'contour' or 'image' for contour and image plots respectively.
col.axis, col.box	Colour for axes and bounding box.
add.boundary	Logical, should filled contours be separated with a boundary line (drawn by contour)?
col.contour, lty.contour, lwd.contour	Colour, line type, and line width for boundary contours.
drawlabels	Logical, contours are labelled if TRUE.
...	Additional arguments to plot.window, title, Axis and box.

Examples

x <- seq(1,100)
y <- seq(1,80)
z <- outer(x,y, function(x,y) sin(x/10) + cos(y / 50))

# contour plot
filled_contour(x,y,z)
