sample.map: Plot The Geographic Location of Samples

Description

This function plot the number of samples collected from different locations that are DISTANT from each other, e.g. samples that collected from distant cities. This function is similar but not the same as sample.locations and sample.sites. The plot will also show the sample size of each location.

Usage

sample.map(meta, siteID="City", maptype="roadmap",  
           lat="Latitude", lon="Longitude", zoom=3, 
           file=NULL, ext=NULL, width=10, height=10)

Arguments

meta

siteID

IDs of sampling sites for each unique pair of longitude and latitude.

maptype

maptype to use, see also get_map.

lat

latitude of each sampling location

lon

zoom

map zoom, an integer from 3 (continent) to 21 (building). see also get_map.

file

the file path where the image should be created (see ?RAM.plotting).

ext
