Google Pie Chart with R \Sexpr{googleChartName <- "piechart"} \Sexpr{gvisChartName <- "gvisPieChart"}

Description

Usage

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

Arguments

data

a data.frame to be displayed as a pie chart

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 for Google Pie Charts, 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")))}

## Doughnut chart - a pie with a hole
Pie2 <- gvisPieChart(CityPopularity, options=list(
                    slices="{4: {offset: 0.2}, 0: {offset: 0.3}}",
                    title='City popularity',
