If you're willing to step outside R, there is a free program called DNRGarmin can take a comma separated file as a .txt and convert it to .kml for import into google earth.

You can find it here:

http://www.dnr.state.mn.us/mis/gis/tools/arcview/extensions/DNRGarmin/DNRGarmin.html

so in R:

my.geo.data <- all.my.data[ c("unique.id", "lats", "longs")]

write.csv( my.geo.data, file = "myGeoData.txt")

open DNRGarmin,

File -> Load From -> File -> myGeoData.txt Then, File -> Save to -> File -> myGeoData.kml

@rcs's advice re: WGS84 applies for this answer too.

Good luck
