bbox_tran: Generate bounding box for Neotoma

In PalEON-Project/stepps-cal: Spatially explicit vegetation reconstruction using proxy pollen data

Description

From a vegetation matrix with x and y columns (or lat/long), generate a bounding box to be used for the loc parameter in the neotoma function get_dataset().

Usage

bbox_tran(x, coord_formula = "~ x + y", from, to)

Arguments

x	A data.frame or matrix with the vegetation data and its coordinates.
coord_formula	The formula, as a string
from	The object proj4 string (e.g., +init=epsg:4121 +proj=longlat +ellps=GRS80).
to	The target proj4 projection string (e.g., +init=epsg:3175).

Value

A numeric vector, of length 4.

Examples

{
  data(plss_vegetation)

  pol_box <- bbox_tran(plss_vegetation, '~ x + y',
    '+init=epsg:3175',
    '+init=epsg:4326')
}
