plot_RLum.Data.Image: Plot function for an RLum.Data.Image S4 class object

Description

The function provides very basic plot functionality for image data of an RLum.Data.Image object. For more sophisticated plotting it is recommended to use other very powerful packages for image processing.

Details on the plot functions

Supported plot types:

plot.type = "plot.raster"

Uses the standard plot function of R graphics::image. If wanted, the image is enhanced, using the argument stretch. Possible values are hist, lin, and NULL. The latter does nothing. The argument useRaster = TRUE is used by default, but can be set to FALSE.

plot.type = "contour"

This uses the function graphics::contour

Usage

plot_RLum.Data.Image(
  object,
  frames = NULL,
  par.local = TRUE,
  plot.type = "plot.raster",
  ...
)

Value

Returns a plot

Arguments

object

RLum.Data.Image (required): S4 object of class RLum.Data.Image

frames

numeric (optional): sets the frames to be set, by default all frames are plotted. Can be sequence of numbers, as long as the frame number is valid.

par.local

logical (with default): use local graphical parameters for plotting, e.g. the plot is shown in one column and one row. If par.local = FALSE global parameters are inherited.

plot.type

character (with default): plot types. Supported types are plot.raster, contour

...

further arguments and graphical parameters that will be passed to the specific plot functions. Standard supported parameters are xlim, ylim, zlim, xlab, ylab, main, legend (TRUE or FALSE), col, cex, axes (TRUE or FALSE), zlim_image (adjust the z-scale over different images), stretch
