Converts and validates bbox objects or strings into standard format

Accepts a variety of bbox formats, validates that they are numerically sane and returns a vector of floats in c(lonLo, lonLo, latLo, latHi) order. Input can be a vector of floats in c(lonLo, lonHi, latLo, latHi) order or the return value from sp::bbox() or raster::extent().

bboxToVector(bbox = NULL)

Arguments

bbox

bounding box for region of interest.

Value

a vector of floats in c(lonLo, lonHi, latLo, latHi) order.
