Interactive Plot Utility

Plots with emphasis on interactive plots.

Usage

interactivePlot(x, choices = paste("Plot", 1:9), 
    plotFUN = paste("plot.", 1:9, sep = ""), which = "all", ...)

Arguments

x

an object to be plotted.

choices

a character vector of length at most 9, giving descriptive names of the plots for the menu presented to the user.

plotFUN

a vector of the same length as choices, containing functions and/or names of functions. plotFUN[[i]] is called to produce the plot corresponding to choice[i].

which

Which graph(s) should be displayed? One of the character strings "ask" (ask the user) or "all" (produce all plots), or a logical vector in which the positions of the TRUE values designating the plots to produce.

...

additional arguments passed to the FUN or plot function. (2023-10-21 GNB: currently the "..." arguments are not really passed on to the plotting functions.)

Details

If "which" is the character string "ask", then the user is presented with a menu to interactively choose which plot(s) to show. Argument choices is used for the choices in the menu, so they should be informative.

If "which" is equal to "all" all plots are drawn. If "which" is a logical vector, the indicate plots are displayed.

Note that if more plots are to be shown in one window, the arrangement should be made in advance (and cleaned up afterwards), see the examples.

Examples

## Test Plot Function:
   testPlot = function(x, which = "all", ...) {   
     # Plot Function and Addons:
     plot.1 <<- function(x, ...) plot(x, ...)      
     plot.2 <<- function(x, ...) acf(x, ...)
     plot.3 <<- function(x, ...) hist(x, ...)      
     plot.4 <<- function(x, ...) qqnorm(x, ...)
     # Plot:
     interactivePlot(x,
       choices = c("Series Plot", "ACF", "Histogram", "QQ Plot"),
       plotFUN = c("plot.1", "plot.2", "plot.3", "plot.4"),
       which = which, ...)       
     # Return Value:
     invisible()
   }
## Plot:
   # prepare the window and store its previous state
   op <- par(mfrow = c(2, 2), cex = 0.7)
   # produce the plot
   testPlot(rnorm(500))            

   # restore the previous state
   par(op)

   # Try:
   # par(mfrow = c(1,1))
   # testPlot(rnorm(500), which = "ask")

## similar to above but using functions for plotFUN
   testPlot_2 = function(x, which = "all", ...) {   
     interactivePlot(x,
       choices = c("Series Plot", "ACF", "Histogram", "QQ Plot"),
       plotFUN = c(plot.1 = function(x, ...) plot(x, ...),
                   plot.2 = function(x, ...) acf(x, ...),
                   plot.3 = function(x, ...) hist(x, ...),
                   plot.4 = function(x, ...) qqnorm(x, ...) ),
       which = which, ...)       
   
       # Return Value:
       invisible()
   }
   # produce the plot
   op <- par(mfrow = c(2, 2), cex = 0.7)
   testPlot_2(rnorm(500))            

   par(op)
