In biogeo: Point Data Quality Assessment and Coordinate Conversion

Description

An interactive plot with options to select to explore points in the geographical or environmental space. The environmental space is defined by the values of two environmental variables.

Usage

geo2envid(edat, g1, group1 = "Species", group2 = "", 
world, xc = "AP", yc = "AMT", xname = "Annual Precipitation (mm)", 
yname = "Mean Annual Temperature", showrecord = "", 
ext = c(-180, 180, -60, 90))

Arguments

edat	a dataframe containing fields with the following names: ID, x, y, Species, x_original, y_original, Correction, Modified, Exclude and the values of selected environmental variables
g1	the name of the species to select
group1	this is usually the column of species names
group2	a second grouping variable
world	a shapefile of the world, where the column containing the country names must be "NAMES"; see data(wrld_simpl)
xc	the name of the environmental variable to be used on the x-axis of the environmental space
yc	the name of the environmental variable to be used on the y-axis of the environmental space
xname	x-axis label for the environmental space
yname	y-axis label for the environmental space
showrecord	the ID of a selected record to be shown on the map
ext	The extent, which can be specified as c(xmin, xmax, ymin, ymax) default extent c(-180, 180, -90, 90). Alternatively if ext="p" then the extent will be calculated from the coordinates of the points in the dataset.

Details

The selected records are marked with a red dot and ID numbers are shown. Records that are considered to be outliers can be excluded by selecting the record in the environmental space. A menu with various options is produced.

Value

Interactive plot

plotsetup should be run first
