In googleVis: R Interface to Google Charts

Google Combo Chart with R \Sexpr{googleChartName <- "combochart"} \Sexpr{gvisChartName <- "gvisComboChart"}

Description

A chart that lets you render each series as a different marker type from the following list: columns, lines, and area lines.

Usage

gvisComboChart(data, xvar = "", yvar = "", options = list(), chartid)

Arguments

data	a data.frame to be displayed as a columns, line and area chart.
xvar	name of the character column which contains the category labels for the x-axes.
yvar	a vector of column names of the numerical variables to be plotted. Each column is displayed as a separate column, line or area series.
options	list of configuration options, see: \Sexpr[results=rd]{gsub("CHARTNAME", googleChartName, readLines(file.path(".", "inst", "mansections", "GoogleChartToolsURLConfigOptions.txt")))} \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOptions.txt")))}
chartid	character. If missing (default) a random chart id will be generated based on chart type and tempfile

Details

The gvisComboChart function reads a data.frame and creates text output referring to the Google Visualisation API, which can be included into a web page, or as a stand-alone page. The actual chart is rendered by the web browser using SVG or VML.

Value

\Sexpr[results=rd]{paste(gvisChartName)}

returns list of class \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOutputStructure.txt")))}
