Dynamic Graphics with the googleVis Package

Using the googleVis package, dynamic tables, maps, and motion charts can be created to allow the reader to interact with the content. Note that gvis objects, by default, contain <html> and <body> tags which should be removed since Knit HTML does this already. Passing 'chart' to the print function accomplishes this. Also you will need to define results='asis' in your chunk options to ensure the HTML code is not treated as markdown.

Interactive Chart and Map

T <- gvisTable(Exports, options = list(width = 200, height = 280))
G <- gvisGeoChart(Exports, locationvar = "Country", colorvar = "Profit", 
    options = list(width = 360, height = 280, dataMode = "regions"))
TG <- gvisMerge(T, G, horizontal = TRUE, tableOptions = "bgcolor=\"#CCCCCC\" cellspacing=10")

print(TG, "chart")

R and Google Maps

## Hurricane Andrew (1992) storm track with Google Maps
AndrewMap <- gvisMap(Andrew, "LatLong", "Tip", options = list(showTip = TRUE, 
    showLine = TRUE, enableScrollWheel = TRUE, mapType = "hybrid", useMapTypeControl = TRUE))

print(AndrewMap, "chart")

Dynamic Table

## Table with embedded links
PopTable <- gvisTable(Population, options = list(width = 600, height = 300, 
    page = "enable"))

print(PopTable, "chart")
