hello,

what is the meaning of a fullstop in the below R-Ffunction (like in '.GADM')

> library(dismo)
Lade nötiges Paket: raster
Warnmeldungen:
1: Paket ‘dismo’ wurde unter R Version 2.15.3 erstellt
2: Paket ‘raster’ wurde unter R Version 2.15.3 erstellt
> getData
function (name = "GADM", download = TRUE, path = "", ...)
{
    path <- .getDataPath(path)
    if (name == "GADM") {
        .GADM(..., download = download, path = path)
    }
    else if (name == "SRTM") {
        .SRTM(..., download = download, path = path)
    }
    else if (name == "alt") {
        .raster(..., name = name, download = download, path = path)
    }
    else if (name == "worldclim") {
        .worldclim(..., download = download, path = path)
    }
    else if (name == "ISO3") {
        .ISO()[, c(2, 1)]
    }
    else if (name == "countries") {
        .countries(download = download, path = path, ...)
    }
    else {
        stop(name, " not recognized as a valid name.")
    }
}
<bytecode: 0x10f6e5ac>
<environment: namespace:raster>

thanks in advance,
kay
