coordenadas: Prepare object for argument design of spsurvey.analysis()

Description

This function returns an object to feed the argument design when creating an object of class spsurvey.analysis.

Usage

coordenadas(x)

Arguments

x

Object of class SpatialPointsDataFrame from which site ID and XY coordinates are to be returned.

Value

An object of class data.frame containing three columns with names siteID, xcoord, and ycoord.

Details

The argument design used to create object of class spsurvey.analysis requires a series of inputs. However, it can be fed with data about site ID and coordinates. coordenadas() returns a data frame that provides this information, assuming that all other design variables are provided manually in the arguments list.
