spocc (version 0.1.2)

occ_to_sp: Create a spatial points dataframe from a spocc search.

Description

Create a spatial points dataframe from a spocc search.

Usage

occ_to_sp(occObj, coord_string = "+proj=longlat +datum=WGS84",
  just_coords = FALSE)

Arguments

occObj

The resuslts of a spocc search called by occ()

coord_string

A valid EPGS cooridate string from the sp package, the default is WSGS 84

just_coords

Return data frame with specios names and provenance or just a spatial points object, which is the default.

Details

This function will return either a spatial points dataframe or spatial points object. Conversion to spatial points objects allows spocc searches to interact with other spatial data sources. More coordinate system codes can be found at the EPGS registry: http://www.epsg-registry.org/

Examples

library("sp") # for the spplot function below
out <- occ(query = "Populus tremuloides", from = c("inat","gbif"))
out <- fixnames(out, "query")
sp_points <- occ_to_sp(out)
spplot(sp_points, "prov")

### Or see how they line up on a map
library("maptools")
data(wrld_simpl)
plot(wrld_simpl[wrld_simpl$NAME == "United States", ],xlim=c(-70,-60))
out <- occ(query = "Accipiter striatus", from = c("inat","gbif"))
sp_points <- occ_to_sp(out,just_coords=TRUE)
points(sp_points,col=2)
