plotBaseline: Plot method for "baseline" objects

In baseline: Baseline Correction of Spectra

Plot method for "baseline" objects

Description

Plot the original spectrum, the estimated baseline, and the corrected spectrum. Optionally zoom and pan plot, either with arguments or interactively.

Usage

## S4 method for signature 'baseline'
plot(x, y, specNo = 1, grid = FALSE, labels = 1:n, rev.x = FALSE,
     zoom = NULL, ...)
plotBaseline(x, y, specNo = 1, grid = FALSE, labels = 1:n, rev.x = FALSE,
             zoom = list(xz = 1, yz = 1, xc = 0, yc = 0), ...)

Arguments

x	The baseline object to be plotted
y	Unused. Ignored with a warning
specNo	The row number of the spectrum and baseline to plot. Defaults to 1
grid	Logical. Whether to show a grid or not. Defaults to FALSE
labels	Vector. Labels for the x tick marks. Defaults to 1:n
rev.x	Logical. Whether the spectrum should be reversed. Defaults to FALSE
zoom	Either TRUE (only for the plot method), which turns on the interactive zoom controls, or a list with components xz, xc, yz and yc, which specifies the desired zoom and pan. Defaults to no zoom or pan
...	Other arguments. Currently ignored

Details

The normal way to plot baseline objects is to use the plot method. The plotBaseline function is the underlying work-horse function, and is not meant for interactive use.

Note

Because the argument list of any plot method must start with x, y, and the plot method for the baseline class does not use the y argument, all arguments except x must be named explicitly. Positional matching will not work.

Examples

data(milk)
bl <- baseline(milk$spectra[1,, drop=FALSE])
## Not run: 
  # Computationally intensive
