Google Timeline Chart with R \Sexpr{googleChartName <- "timeline"} \Sexpr{gvisChartName <- "gvisTimeline"}

Description

A timeline is a chart that depicts how a set of resources are used over time. One popular type of timeline is the Gantt chart.

Usage

gvisTimeline(
  data,
  rowlabel = "",
  barlabel = "",
  start = "",
  end = "",
  options = list(),
  chartid
)

Arguments

data	data.frame that contains the data to be visualised
rowlabel	a string that refers to the column name in data for the row labels to be used
barlabel	a string that refers to the column name in data for the bar labels to be used
start	number, date or datetime for the start dates
end	number, date or datetime for the end dates
options	list of configuration options. The options are documented in detail by Google online: \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")))}
