In sebkopf/animanipulate: Manipulate and animate plots (an extension of gWidgetsManipulate, a gWidgets port of RStudio's manipulate package).

Description

Due to the event loop structure of tcltk, this only works in the GTK toolkit at the moment.

Usage

manipulate(._expr, ...)

Arguments

._expr	expression to produce output.
...	used to specify controls. See picker, checkbox, slider.

Value

makes output, returns Animanipulate object

Examples

## Not run: 
manipulate(## expression
{
  size <- sqrt.size^2
  y <- get(distribution)(size)
  plot(density(y, bw = bandwidth/100, kernel=kernel),
       axes = axes, ann = label,
       main = paste("kernel:", kernel))
  points(y, rep(0, size))
},
## controls
distribution = picker("rnorm", "rexp"),
kernel = picker("gaussian", "epanechnikov",
                "rectangular", "triangular", "cosine"),
sqrt.size = slider(5, 30, step = 1, init = 10),
bandwidth = slider(5, 200, step = 5, init = 100,
                   label = "bandwith [%]"), # using % here b/c some toolkits only allow integers (GTK is fine with real)
axes = checkbox(TRUE, label="Draw Axes"),
label = checkbox(TRUE, label="Draw Labels")
)

## End(Not run)
