rmGeoIdentity: Remove geographical identity

In ClimMobTools: API Client for the 'ClimMob' Platform

Remove geographical identity

Description

Build a buffer around the a set of geographical coordinates and take a random point around the buffer. The function is used to omit the precise location of tricot participants but keeping a close distance to the trial environment.

Usage

rmGeoIdentity(longlat, dist = 0.015, nQuadSegs = 2L, seed = NULL, ...)

Arguments

longlat	a data.frame or matrix with geographical coordinates long lat
dist	numeric, buffer distance for all lonlat
nQuadSegs	integer, number of segments per quadrant
seed	integer, the seed for random number generation. If NULL (the default), ClimMobTools will set the seed randomly
...	further arguments passed to sf methods

Value

A data frame with the random coordinates long lat within the buffer

Examples

library("sf")

xy = matrix(c(11.097799, 60.801090,
               11.161298, 60.804199,
               11.254428, 60.822457),
             nrow = 3, ncol = 2, byrow = TRUE)

rmGeoIdentity(xy, seed = 1501)

#' the function also handles NAs

xy2 = matrix(c(11.097799, 60.801090,
                NA, NA,
                11.161298, 60.804199,
                11.254428, 60.822457,
                11.254428, NA),
              nrow = 5, ncol = 2, byrow = TRUE)

rmGeoIdentity(xy2)
