Draw Map of Plot Locations

Description

map draws a simple vector background map and plot locations. ellipsoidhull computes the ellipsoid hull or spanning ellipsoid such that all given points lie just inside or on the boundary of the ellipsoid and adds it to a map.

quicklook opens a browser window and plots pushpins of plot coordiantes on top of ‘Google Maps’.

Usage

## S4 method for signature 'Vegsoup'
quicklook(x)
## S4 method for signature 'VegsoupPartition'
ellipsoidhull(x, tol = 0.01, maxit = 5000, ret.wt = FALSE,
  ret.sqdist = FALSE, ret.pr = FALSE)

Arguments

x

Vegsoup* or for ellipsoidhull a 'VegsoupPartition' object.

...

Arguments passed to map in package maps.

tol, maxit, ret.wt, ret.sqdist, ret.pr

Arguments to ellipsoidhull in package cluster.

Details

ellipsoidhull is a simple wrapper for function ellipsoidhull in package cluster. The main purpose of the function is to visualize partitions on a map.

Function quicklook opens a browser window and plots pushpins of plot centers on top of ‘Google Maps’. See gvisMap in package googleVis for details.

Value

map creates a map plot.

ellipsoidhull adds ellipses to the current plot. The function returns a list of objects of class "ellipsoid" for all partitions having 3 ore more points (plots), otherwise a matrix of ploting coordinates representing each plot location. See ellipsoidhull for details.
