In manipulate: Interactive Plots for RStudio

Description

Interactive plotting functions for use within RStudio.

Details

The manipulate function accepts a plotting expression and a set of controls (e.g. slider, picker, checkbox, or button) which are used to dynamically change values within the expression. When a value is changed using its corresponding control the expression is automatically re-executed and the plot is redrawn.

For example, to create a plot that enables manipulation of a parameter using a slider control you could use syntax like this:

manipulate(plot(1:x), x = slider(1, 10))

After this code is executed the plot is drawn using an initial value of 1 for x. A manipulator panel is also opened adjacent to the plot which contains a slider control used to change the value of x from 1 to 10.

Examples

## Not run: 

## Create a plot with a manipulator
manipulate(plot(1:x), x = slider(5, 10))

## Using more than one slider
manipulate(
  plot(cars, xlim=c(x.min,x.max)),
  x.min=slider(0,15),
  x.max=slider(15,30))

## Filtering data with a picker
manipulate(
  barplot(as.matrix(longley[,factor]),
          beside = TRUE, main = factor),
  factor = picker("GNP", "Unemployed", "Employed"))

## Create a picker with labels
manipulate(
  plot(pressure, type = type),
  type = picker("points" = "p", "line" = "l", "step" = "s"))

## Toggle boxplot outlier display using checkbox
manipulate(
  boxplot(Freq ~ Class, data = Titanic, outline = outline),
  outline = checkbox(FALSE, "Show outliers"))

## Combining controls
manipulate(
  plot(cars, xlim = c(x.min, x.max), type = type,
       axes = axes, ann = label),
  x.min = slider(0,15),
  x.max = slider(15,30, initial = 25),
  type = picker("p", "l", "b", "c", "o", "h", "s", "S", "n"),
  axes = checkbox(TRUE, "Draw Axes"),
  label = checkbox(FALSE, "Draw Labels"))

## End(Not run)
