plot.fds: Plot functional objects

In rainbow: Bagplots, Boxplots and Rainbow Plots for Functional Data

Plot functional objects

Description

Plot functional curves.

Usage

## S3 method for class 'fds'
plot(x, plot.type = c("functions", "time", "depth", "density"),
  col = NULL, type = "l", lty = 1, xlab = x$xname, ylab = x$yname, 
  pch = c(1:9,0, letters, LETTERS), add = FALSE, index,     
  colorchoice = c("rainbow", "heat.colors", "terrain.colors", 
  "topo.colors", "cm.colors", "rainbow_hcl", "gray", "sequential_hcl", 
  "heat_hcl", "terrain_hcl", "diverge_hcl"), plotlegend = FALSE, 
  legendpos = "topright", ncol = 1, ...)
## S3 method for class 'fds'
lines(x, type = "l", index, ...)
## S3 method for class 'fds'
points(x, type = "p", index, ...)  

Arguments

x	An object of class fds or fts.
plot.type	Type of plot. See details for more explanations.
col	Colors to use in plot. Default in plot.fds is to use a rainbow color palette with the number of colors equal to the number of functions.
type	1-character string giving the type of plot desired.
lty	The line type.
xlab	A title for x axis.
ylab	A title for y axis.
pch	Either an integer specifying a symbol or a single character to be used as the default in plotting points.
add	If add = TRUE, it plots a line or points.
index	Index of a specific curve that is plotted as a line or points.
colorchoice	Color palette used for drawing the rainbow plot.
plotlegend	Add a legend to the graph.
legendpos	Position of legend.
ncol	Number of column in the legend.
...	Other plotting parameters passed to par.

Details

If plot.type = "functions", then functions are plotted using a rainbow color palette so the first few functions are shown in red, followed by orange, yellow, green, blue and indigo with the last few functions plotted in violet.

If plot.type = "time", then each value of x is shown as a separate time series in a time plot.

If plot.type = "depth", then functions are first ordered by depth and then plotted using a rainbow color palette.

If plot.type = "density", then functions are first ordered by density and then plotted using a rainbow color palette.

Value

Function produces a plot.
