data(Kenya_veg)

## Plots containing Podocarpus observations
Kenya_veg@species <- subset(Kenya_veg@species, grepl("Podocarpus", TaxonName),
	slot="names")
	
Kenya_veg <- subset(Kenya_veg, TaxonUsageID %in%
	Kenya_veg@species@taxonNames$TaxonUsageID, slot="samples")

# }
# NOT RUN {
vegtable2kml(Kenya_veg, "Podocarpus.kml")
