 To put data onto Google Earth then you need to make a KML file. You
can probably do this with writeOGR from the rgdal package, or the kml*
functions in maptools - but if you want to do anything fancy then you
need to write your own KML file from your data. I have found the
'brewer' package useful for writing templates to make KML files.

 You'll have to study the KML specification from Google as well.
