master_matrix

new_master_matrix

date.frame with information about geographic location of
raster cells, initial environmental data, and if available, the first two
principal components derived from an analysis done with environmental values.

data_matrix

data.frame containing sites that must be included
in posterior selections of sites for the survey system. Columns must be:
"Sites", "Longitude", "Latitude", in that order. Default = NULL.

preselected_sites

SpatialPolygons* object representing the region of interest.

region

SpatialPolygons* object used. Default = NULL.

mask

SpatialPolygonsDataFrame representing the grid of the
raster layers used, which will be used for plotting purposes.

raster_base

results of principal component analysis performed with
values from raster layers used. Default = NULL.

Constructor of S3 objects of class master_matrix

A collection of tools that allows users to plan systems of sampling
sites, increasing the efficiency of biodiversity monitoring by considering
the relationship between environmental and geographic conditions in a
region. The options for selecting sampling sites included here differ from
other implementations in that they consider the environmental and geographic
conditions of a region to suggest sampling sites that could increase the
efficiency of efforts dedicated to monitoring biodiversity. The methods
proposed here are new in the sense that they combine various criteria and
points previously made in related literature; some of the theoretical and
methodological bases considered are described in:
Arita et al. (2011) <doi:10.1111/j.1466-8238.2011.00662.x>,
