contains the extension variables (Locator: "d") which give the extension
of the cell (along each space direction), centered on each sample of the Db.
- db.selhull: Performs a selection on a Db according to the convex hull of the
active data of a second Db.
- model.pgs.sample: To calculate the covariance of indicators in the
PluriGaussian model
Bug Fixes :
-----------
- Prevent wrong activation codes to be found
- Correction on the display of variograms: vertical axis should start at 0
for (symmetric) functions such as variogram, madograms ...
Release 9.1.1
=============
New functions :
---------------
Bug Fixes :
-----------
- Try to be compatible with SUSE Linux distribution
- When performing simulations using Turning Bands on targets when the
Model contains some Nugget Effect, it is important that the Conditional
Simulations remain exact if a target coincides with a grid node.
The post-process correction which checks that property has been corrected.
Release 9.1.0
=============
New functions :
---------------
- No more need Rcpp package dependency
Bug Fixes :
-----------
- Link statically to Rcpp to fix dynamic load Rcpp.so on Linux
- model0.start modification to handle drift list
Release 9.0.8
=============
Bug Fixes :
-----------
- Change the way to find activation codes to prevent a virtual adapter
to be choosen
- When performing simulations using Turning Bands on targets when the
Model contains some Nugget Effect, it is important that the Conditional
Simulations remain exact if a target coincides with a data point.
The post-process correction which checks that property has been corrected.
Release 9.0.7
=============
New functions :
---------------
GUI.Krige.R gives a complete interface for performing Kriging and/or Simulation
with different options. This is a tentative version which will be improved and completed in future versions.
Modification in functions :
---------------------------
- db.digit returns the coordinates of the digitized points as the return value.
Bug Fixes :
-----------
- Fix R 2.15.2 and Rcpp 0.10.2 compatibility
Release 9.0.6
=============
New functions :
---------------
Modification in functions :
---------------------------
Improvement in the Turning Band simulation gaining a lot of time in the case
of simulations performed on a regular grid.
Bug Fixes :
-----------
Release 9.0.5
=============
New functions :
---------------
Modification in functions :
---------------------------
Bug Fixes :
-----------
Minor
Release 9.0.4
=============
New functions :
---------------
- melem.characteristics(): provides the various parameters of a given basic
structure (used to identify the parameters to be defined)
- model.maxdist(): returns the maximum distance of the definition of a model.
This is used in particular to perform a graphic representation of a model
(with no experimental variogram information to give the maximum distance)
- util.rotmat(): checks if the input (square) matrix is a rotation matrix
- util.defpositive(): checks if the input (square) matrix if definite positive
- util.nonneg.matrix(): checks if the input (rectangular) matrix is non negative
- db.append(): concatenates the contents of a data.frame to an already
existing Db.
A major improvement is the introduction of Graphic Interfaces (which require
the package gWidgets to be installed). These interfaces contain:
- GUI.db for editing a Db
- GUI.model for editing a model (or creating a new one)
- GUI.neigh for editing a neighborhood (or creating a new one)
Modification in functions :
---------------------------
- In vmap.grid(), the Variogram Map (stored in a new Db Grid file) can be
calculated in 3-D (if the input grid is defined in 3-D).
- In all variogram and vmap calculation functions, the non-centered covariance
tool has been added (calcul = "covnc")
Bug Fixes :
-----------
Release 9.0.3
=============
New functions :
---------------
Modification in functions :
---------------------------
- in db.locate, the algorithm has changed when modifying a locator and setting
it equal to the locator of another variable: the system tends to keep the
previous locator type and simply move its rank (to upper value).
Bug Fixes :
-----------
- The DESCRIPTION file includes (back) the dependency upon "graphics" which
appears to be mandatory.
Release 9.0.2
=============
Bug Fixes :
-----------
- Suppress the help file RGeos-package.Rd
Release 9.0.1
=============
New functions :
---------------
Modification in functions :
---------------------------
- in function simbool(), possibility to define the value assigned to the
background.
Bug Fixes :
-----------
- in function db.plot() performed on a grid, possibility to represent grid
cells with undefined values.
Release 9.0.0
=============
New functions :
---------------
The essential improvement of this release is the presence of the new forum
on which you can post your suggestions or the bugs that you may have
encountered.
- vmap.calc(): calculate the variogram map from values defined on
isolated points.
- Fix of the Rcpp dependency on all platforms.
- Additional covariance functions:
. REG1D: calculated as the 1-D covariance of the residuals when subtracting
a moving average from a regionalized variogram following a linear variogram.
It shows a moderate hole effect although it does not involve any
periodicity.
. PENTA: spherical model in R7 after "montee" of order 4
. SPLINE2: Spline generalized covariance in IRF2
Modification in functions :
---------------------------
- Adding the possibility to force the printout of a grid to be performed
considering the grid nodes as isolated points. Therefore the file will
contain the nodes coordinates.
Bug Fixes :
-----------
- The ASCII file obtained using neigh.write() now produces the anisotropy
of the neighborhood search ellipse (and its rotation) correctly.
