phcfM R package
phcfM is an R package for modelling anthropogenic deforestation. It
was initially developed to obtain REDD+ baseline scenarios of
deforestation for the programme holistique de conservation des forêts
à Madagascar (from which the package was named after). It includes
two main functions:
demography(), to model the population growth with time in a
hierarchical Bayesian framework using population census data and
Gaussian linear mixed models.
deforestation(), to model the deforestation process in a
hierarchical Bayesian framework using land-cover change data and
Binomial logistic regression models with variable time-intervals
between land-cover observations.
Code and manual
The last stable version of the
phcfM R package (
phcfM_1.2) is officially available for several operating systems (Unix, Windows and Mac OSX) on the Comprehensive R Archive Network (CRAN).
The source code and manual for the testing version
is available here:
A GRASS location (
phcfM_SM) and two mapsets with geographical data
study_area_4) are available to illustrate the
use of the
phcfM R package. Associated to the GRASS location, a
./scripts) includes the data and the R/GRASS scripts used
for the demographic and deforestation models.
