ILS (version 0.3)

plot.ils.fqcs: Plotting method for 'ils.fqcs' objects

Description

Generic function to plot objects of 'ils.fqcs' class. Results of functional ILS studies are graphically shown.

Usage

# S3 method for ils.fqcs
plot(x, type = "l", xlab = NULL, ylab = NULL, legend = TRUE, col = NULL, ...)

Arguments

x

An object of class ils.fqcs (Functional Quality Control Statistics).

type

1-character string giving the type of plot desired. The following values are possible for fdata class object: "l" for lines (by default), "p" for points, , "o" for overplotted points and lines, "b", "c" for (empty if "c") points joined by lines, "s" and "S" for stair steps and "h" for histogram-like vertical lines. Finally, "n" does not produce any points or lines. The following values are possible for fdata2d class object: "image.contour" (by default) to display three-dimensional data and add the contour lines, "image" to display three-dimensional data, "contour" to display a contour plot, "persp" to display a perspective plots of a surface over the x-y plane and "filled.contour" to display a contour plot with the areas between the contours filled in solid color.

xlab

Title for the x axis.

ylab

Title for the y axis.

legend

Logical argument. Default is TRUE then The legend default is used.

col

Color specifications.

...

Other arguments to be passed to or from methods.
