In hafen/cardoonTools: cardoonTools

Description

Take a plot expression or object and turn it into a base64 encoded png string for embedding in a browser

Usage

cardoonPlot(plotObj, type = c("png", "pdf"), width = 480, height = 480,
  res = 72, ...)

Arguments

plotObj	a lattice or ggplot object, or an expression of R base plotting commands
type	the type of plot to create (currently png or pdf)
width	width of plot, in pixels
height	width of plot, in pixels
res	nominal resolution in ppi which will be recorded in the file, if a positive integer
...	arguments passed to png or pdf

Value

a base64 encoded png string

Examples

cardoonPlot(expression(plot(1:10)))
myPlotExpr <- expression({
   plot(1:10)
   abline(0, 1)
})
cardoonPlot(myPlotExpr)

# passing additional arguments to png
cardoonPlot(expression(plot(1:10)),
   width = 800, height = 400, res = 150)

# using lattice:
cardoonPlot(xyplot(rnorm(10) ~ rnorm(10)))
# pass lattice object
p <- dotplot(variety ~ yield | year * site, data=barley)
cardoonPlot(p)

# using ggplot
cardoonPlot(qplot(mpg, wt, data = mtcars))
# pass ggplot object
p <- qplot(mpg, wt, data = mtcars)
cardoonPlot(p)
