..The dismo package is awesome: with some short lines of code you can read & map species distribution data from GBIF (the global biodiversity information facility) easily:

library(dismo)

# get GBIF data with function:
myrger <- gbif("Myricaria", "germanica", geo = T)

# check:
str(myrger)

# plot occurrences:
library(maptools)
data(wrld_simpl)
plot(wrld_simpl, col = "light yellow", axes = T)
points(myrger$lon, myrger$lat, col = "red", cex = 0.5)
text(-140, -50, "MYRICARIA\nGERMANICA")

... I thought this geocoding-bit might be worth sharing (found HERE when searching the web for dismo-documentation).

library(dismo)

x <- geocode("Bozner Platz, Innsbruck, Tirol, Austria")
e <- extent(unlist(x[4:7]))
g <- gmap(e, type = "satellite")

plot(g)
