The gvisIntensityMap 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.
Usage

gvisIntensityMap(data, locationvar = "", numvar = "",
options = list(), chartid)
Arguments
data
a data.frame. The data has to have at least two
columns with location name (locationvar) and any number of
numeric columns (numvar) to be mapped.
locationvar
column name of data with the geo locations to be
analysed. The location has to contain country ISO codes or USA state codes.
numvar
column names of data with the numeric values to be
displayed.
options
list of configuration options for Google Intensity Map.
gvis.editora character label for an
on-page button which opens an in-page dialog box that enables
users to edit, change and customise the chart. By default no
value is given and therefore no button is displayed.
Further possible components are, taken from
https://google-developers.appspot.com/chart/interactive/docs/gallery/intensitymap.html#Configuration_Options:
colorsa JSON array of strings. The colors to use for each
tab. An array of strings. Each element is a string in the format
#rrggbb. For example '#00cc00'.
heighta number. Default 220. Height of the map in
pixels. The maximum height of the visualization is 220. Note
that this height assumes a one-row tab. If your tab text is
long, it will wrap the tab to multiple lines, and the extra
lines will exceed the specified height.
regiona string. Default 'world'. The required
region. Possible values are: 'world', 'africa', 'asia',
'europe', 'middle_east', 'south_america', and 'usa'.
showOneTabboolean. Default FALSE. The
intensity map can display one or more numeric columns. Each
column is displayed as a separate map, and tabs on top enable
selection of which map to show. When the data table contains
only one numeric column, the tabs are not displayed. To display
tabs even for a single numeric column, set this option to TRUE.
widtha number. Default 440. Width of the map in
pixels. Note: The maximum width of the visualization is 440.
chartid
character. If missing (default) a random chart id will be generated based on
chart type and tempfile
Value
gvisIntensityMap returns list of class "gvis" and "list".
An object of class "gvis" is a list containing at least the following components:
type
Google visualisation type, here 'IntensityMap'
chartid
character id of the chart object. Unique chart
ids are required to place several charts on the same page.
html
a list with the building blocks for a page
headera character string of a html page header:
<html>...<body>,
charta named character vector of the chart's building blocks:
jsHeaderOpening <script> tag and
reference to Google's JavaScript library.
jsDataJavaScript function defining the input
data as a JSON object.
jsDrawChartJavaScript function
combing the data with the visualisation API and user
options.
jsDisplayChartJavaScript function calling the
handler to display the chart.
jsFooterEnd tag </script>.
jsChartCall of the jsDisplayChart
function.
divChart<div> container to embed the chart
into the page.
captioncharacter string of a standard caption,
including data name and chart id.
footercharacter string of a html page footer:
</body>...</html>, including the used R and googleVis version
and link to Google's Terms of Use.
