plot.feem: Plot a FEEM object

In albatross: PARAFAC Analysis of Fluorescence Excitation-Emission Matrices

Plot a FEEM object

Description

Plot a 2D fluorescence intensity surface as a pseudo-colour image.

Usage

## S3 method for class 'feem'
plot(
  x, xlab, ylab, cuts = 128,
  col.regions = marine.colours(256), ...
)
## S3 method for class 'feemcube'
plot(
  x, xlab, ylab, cuts = 128,
  col.regions = marine.colours(256), as.table = TRUE, ...
)
## S3 method for class 'feem.resid'
plot(
  x, ..., at, col.regions = diverging.colours(256)
)

Arguments

x	An FEEM object.
xlab	The x-axis label for the plot, with a sane default.
ylab	The y-axis label for the plot, with a sane default.
cuts	The number of distinct levels the intensity would be divided into, areas between them assigned different colours.
col.regions	The palette to take the colours from, a character vector of R colour specifications.
at	The breakpoints in the intensity values. For residual plots, automatically set in a symmetric manner, ignoring the cuts argument.
as.table	Whether to draw the panels left to right, top to bottom. (Otherwise they are drawn left to right, bottom to top.)
...	Passed as-is to levelplot.

Value

A lattice plot object. Its print or plot method will draw the plot on an appropriate plotting device.
