gvisGauge() R function from [googleVis]

Google Gauge with R googleChartName <- "gauge"

gvisChartName <- "gvisGauge"

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.


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:

gsub("CHARTNAME", googleChartName, readLines(file.path(".", "inst","mansections", "GoogleChartToolsURLConfigOptions.txt")))

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

Returns

paste(gvisChartName) returns list of class

paste(readLines(file.path(".", "inst", "mansections","gvisOutputStructure.txt")))

Examples


## Please note that by default the googleVis plot command
## will open a browser window and requires an internet
## connection to display the visualisation.

Gauge1 <- gvisGauge(CityPopularity, options=list(min=0, max=800, greenFrom=500,
                    greenTo=800, yellowFrom=300, yellowTo=500,
                    redFrom=0, redTo=300))
