occ2sp: Create a spatial points dataframe from a spocc search

In mapr: Visualize Species Occurrence Data

Description

Create a spatial points dataframe from a spocc search

Usage

occ2sp(x, coord_string = "+proj=longlat +datum=WGS84", just_coords = FALSE)

Arguments

x	The resuslts of a spocc search called by spocc::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

Examples

## Not run: 
### See points on a map
library("maptools")
library("spocc")
data(wrld_simpl)
plot(wrld_simpl[wrld_simpl$NAME == "United States", ], xlim = c(-70, -60))
out <- occ(query = "Accipiter striatus", from = c("vertnet", "gbif"),
  limit = 50)
xx <- occ2sp(out, just_coords = TRUE)
points(xx, col = 2)

## End(Not run)
