Usage

addStyleMap(id, idn, idh)

Arguments

id	Mandatory. Define style id. kml features will need to reference this id to use the defined style. You must choose a unique style id.
idn	Mandatory. Reference the normal(non-highlighted) style id. If you have not yet created this style, you must created it in order for it to be linked.

mykml = RKmlObject()

#add styles. labelstyle1 will be the normal style, labelstyle2 will be the mouseover style
mykml$addLabelStyle(styleid = "labelstyle1", color = "red", transparency = .5, scale = 1)
mykml$addLabelStyle(styleid = "labelstyle2", color = "green", transparency = 1, scale = 2)

#make icon transparent(invisible) for the mouseover style
mykml$addIconStyle(styleid = "labelstyle2", color = "white", transparency = 0)

#add map style so mouseover effects can be acheived
mykml$addStyleMap(id = "my_mouseover_style", idn = "labelstyle1", idh = "labelstyle2")

#create points so styles can be visualized
x = data.frame(cbind(c(45.9178, 46.807), c(-59.967, -60.321), c("Example1", "Example2"), c("Louisbourg", "Neil's Harbour" )))
names(x) = c("lat", "lon", "name", "description")
