slider.brush: interactive brushing functions

Description

These functions compute a pairs plot or a simple xy-plot and open a slider control widget for brushing.

slider.brush.pairs computes a pairs plot; the user defines an interval for one of the variables and in effect all data points in this interval will be recolored.

slider.brush.plot.xy computes an xy-plot; the user defines a interval for a third variable z and all points (x,y) will be recolored red if the z value is in the interval.

Usage

slider.brush.pairs(x, ...)
  slider.brush.plot.xy(x, y, z, ...)

Arguments

…

new settings for global graphics parameters

x

matrix or data frame or vector

y

vector of y values if x is not a matrix

z

vector of z values if x is not a matrix

Value

a message about the usage

Details

slider.brush.pairs draws a pairs plot of the data set x. The first slider defines the lower limit of the interval and the second its width. By the third slider a variable is selected. All data points for which the selected variable is in the interval are recolored red.

slider.brush.plot.xy draws an xy-plot of the data set x. The first slider defines the lower limit of the interval of z values and the second one its width. All data points for which the variable z is in the interval are recolored red.
