rangeMapper (version 0.2-8)

assemblageFetch-methods: Function assemblageFetch retrieves the species set of an arbitrary canvas cell

Description

Function assemblageFetch retrieves the species set, and the data associated with it, of an arbitrary canvas cell optionally with the associated life history data

Examples

require(rangeMapper)

projName = "wrens.sqlite"
projLoc = paste(tempdir(), projName, sep = .Platform$file.sep)

dbcon = rangeMap.start(file = projName,dir = tempdir() , overwrite = TRUE)
f = system.file(package = "rangeMapper", "extdata", "wrens", "vector_combined")
global.bbox.save(con = dbcon, bbox = f) 
gridSize.save(dbcon, gridSize = 3) 
canvas.save(dbcon) 
data(wrens)
bio.save(con = dbcon, loc = wrens ,  ID = "sci_name")
r = readOGR(f, "wrens", verbose = FALSE)
processRanges(spdf = r, con =  dbcon, ID = "sci_name")
rangeMap.save(dbcon)

sr = rangeMap.fetch(dbcon)
image(sr, axes = TRUE); grid()

p = list(x = -76.39, y = 9.26)
# or use locator:  p =  locator(1) 

xy = SpatialPoints( do.call(cbind, p), proj4string = CRS("+proj=longlat +datum=NAD83 +no_defs ") )
af = assemblageFetch(rangeMap(projLoc) , xy)
points(p, col = 4, cex = 2)
print(af)

af = assemblageFetch(rangeMap(projLoc) , xy, "wrens")
print(af[, c(1, 4, 6:8)])
