R Packages
pgirmess
is a package of miscellaneous
functions
developped in R for data handling and analysis in ecology. They have
been used in
the course of on going researches carried out at the Department
of Chrono-environment
of the University of
Franche-Comté as and when required sometimes with several
contributors (mentioned in the documentation). The last stable version
of this package can be downloaded
from here and the
beta version under developement if available.
The stable version and a pdf reference manual are also accessible via
the
CRAN project.
The
package name comes from the acronym Patrick GIRaudoux MESS (the content
reality and an indirect hommage to more essential packages, eg MASS,
etc.). The best we can is done to optimise each function and
pgir must be blamed for any misworking.
pgirbric
is a package with
functions not intended to be published on CRAN for some reasons (eg too
much device specific or still to improve or deprecated in other
packages, etc.). The
name is an
acronym of Patrick GIRaudoux BRIColage, the latter a French name for
'do-it-yourself' which may be another kind of mess, or for BRICk, some
functions seen as brick to build something more general later.
Same comments as above about misworkings.
Working prototypes of shell scripts to run within GRASS 63 or >
Those files must be copied into a folder
visible with PATH eg. under linux have a "scripts"
folder in your home directory and add GRASS_ADDON_PATH=~/scripts
to /usr/lib/grass/etc/Init.sh. To specify rights e.g. chmod a+x r.what.buff2 before running it may be necessary.
r.what.vbuff2 generates a text file of the frequency of each category of a raster map
within various radius buffers computed on vector point sites. A
circular buffer is created around each point location of the vector file
and the final output is text file of 4 columns: col 1 = radius, col 2 = point
ID, col 3 = pixel category value, col 4 = pixel count
corresponding to this value. Category * is the null value.
r.what.vpoly permits to generate a text file of the frequency of each category of a raster map
for areas covered by polygon vector objects. The output is a text file
of 3 columns: col 1 = polygon ID number, col 2 = category
value, col 3 = pixel count
corresponding to this category. Category * is the null value.

I am often asked which procedure is used for multiple comparisons in kruskalmc.
You'll find a citation of "Siegel and Castellan (1988) Non
