Google Gauge with R \Sexpr{googleChartName <- "gauge"} \Sexpr{gvisChartName <- "gvisGauge"}

Description

The gvisGauge 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.

Usage

gvisGauge(data, labelvar = "", numvar = "", options = list(), chartid)

Arguments

data	a data.frame to be displayed as a gauge
labelvar	name of the character column which contains the category labels for the slice labels.
numvar	a vector of column names of the numerical variables of the slice values.
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

Value

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

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