Arguments

SP

object of SpatialPointsDataFrame-class with associated coordinate reference systems and minimum three attributes: semi-major axis, semi-minor axis, and orientation in degrees.

filename

the name of the output htm or html file. If filename is not defined the function creates temporary file.

zcol

variable column names, or column numbers after removing spatial coordinates from x@data: 1 refers to the first non-coordinate column. Attribute names or numbers of columns contains semi-major axis, semi-minor axis, and orientation in degrees respectively

add

logical; if TRUE the result of the function will be a list stored as variable in the R. It is possible to combine more layers in the one plot, previously saved output from plotGoogleMaps should be given in the previousMap attribute.

previousMap

previously saved variable from plotGoogleMaps when attribute add is TRUE. It is solution for combining more than one layers in the one plot.

scale_e

if is 10 then ellipses is drown 10:1

colPalette

colours to be used to fill plotting symbols; numeric vector of same size like key.entries

strokeColor

the color to draw the border of circle (the plotting symbols), NULL for no border

strokeOpacity

the stroke opacity between 0.0 and 1.0

fillOpacity

the fill opacity between 0.0 and 1.0

strokeWeight

the stroke width in pixels

geodesic

render each edge as a geodesic (a segment of a 'great circle')

clickable

indicates whether this plotting symbol handles click events

zIndex

the zIndex compared to other polygons

map.width

the width of the map. Can be in percent or in pixels (px)

map.height

the height of the map. Can be in percent or in pixels (px)

layerName

the name of the layer. Layer name appears on the check box for switching layer of and on in output htm.

control.width

the width of the part of htm for controlling layer (legend, opacity,...) Can be in percent or in pixels (px).

control.height

the height of the part of htm for controlling layer (legend, opacity,...) Can be in percent or in pixels (px).

zoom

the initial Map zoom level.Zoom levels between 0 (the lowest zoom level, in which the entire world can be seen on one map) to 19 (the highest zoom level, down to individual buildings) are possible within the normal maps view. Argument fitBounds should be FALSE.

fitBounds

sets the maps to fit to the boundary box values of sp object

mapTypeId

the initial Map mapTypeId. 'HYBRID' - map type displays a transparent layer of major streets on satellite images. 'ROADMAP' - map type displays a normal street map. 'SATELLITE' - map type displays satellite images. 'TERRAIN' - map type displays maps with physical features such as terrain and vegetation.

disableDoubleClickZoom

enables or disables zoom and center on double click.

draggable

if FALSE, prevents the map from being dragged

keyboardShortcuts

if FALSE, prevents the map from being controlled by the keyboard.

mapTypeControlOptions

the initial display options for the Map type control. 'DEFAULT' - uses the default map type control. 'DROPDOWN_MENU' - a dropdown menu for the screen realestate conscious. 'HORIZONTAL_BAR' - the standard horizontal radio buttons bar.

navigationControl

enabled or disabled state of the navigation control

navigationControlOptions

the initial display options for the navigation control. 'ANDROID' - the small zoom control similar to the one used by the native Maps application on Android. 'DEFAULT' - the default navigation control. The control which DEFAULT maps to will vary according to map size and other factors. It may change in future versions of the API. 'SMALL' - the small, zoom only control. 'ZOOM_PAN' - the larger control, with the zoom slider and pan directional pad.

scaleControlOptions

the initial display options for the scale control.

noClear

if TRUE, do not clear the contents of the Map div.

scrollwheel

if FALSE, disables scrollwheel zooming on the map.

streetViewControl

the initial enabled or disabled state of the Street View pegman control

legend

if FALSE, disables legend.

control

if FALSE, disables control.

InfoWindowControl

see https://developers.google.com/maps/documentation/javascript/reference#InfoWindowOptions

api

see https://developers.google.com/maps/documentation/javascript/tutorial

openMap

if TRUE map is browesed by default browser

Value

This function returns a list with HTML, JavaScript, Google Maps API key and else what is necessary for the final web map. The second output is htm file ready to use stored in working direcoty.
