-The Soil Texture Wizard
-change log. From 2009/10/09. Most recent changes first / on top.
-Julien MOEYS
------------------------------------------------------------------------------------------
-
-o version 1.2.9
-
- 20120307 Removed a useless usage of installed.packages()
- 20120308 Compact the vignettes before R CMD build
-
-o version 1.2.8
-
- 20120125 New attempt to fix xtable package dependence in the vignette.
-
-o version 1.2.7
-
- 20120106 no visible change (fixed package dependance in vignette) + corrected TT.plot()
- example for Spanish language.
-
-o version 1.2.6
-
- 20111112 Added the German (GDR) texture triangle for forest soils:
- "Standortserkundungsanweisung SEA 1974 (DE)"
-
-o older versions
-
- 20111109 New attempt to fix problems while loading the Polish texture triangle
- under Mac/Darwin and freeBSD.
-
- 20111101 Fixed a potential infinite loop problem in the texture transformation
- functions based on "drc"
-
- 20111101 Improved handling / loading of the Polish triangle (is not working under
- Mac). Added the polih triangle to the vignette.
-
- 20100610 New function TT.polygon.centroids() used for a smater calculation
- of the texture class centroid for better placement of the texture
- classes labels (used by TT.classes(), itself used by TT.plot()).
-
- 20100607 Added the Romanian texture triangle to the list of pre-defined texture
- triangles, and the Romanian language to the list of possible languages
- for the texture triangle title and axis labels. many thanks to
- Rosca Bogdan (Romanian Academy, Iasi Branch, Geography team) for providing
- the code and translation.
-
- 20100513 Accuracy problems detected in TT.points.in.classes() for texture data
- located right on the boundary of the triangle (or some texture classes),
- with some digits after the decimal: due to non-exact trigonometric
- calculations (around 1E-15), these points may not be classified
- as on the border, or even belonging to the texture class. These
- accuracy problems can be partially fixed by a new parameter of
- TT.points.in.classes(), 'texture2xy' that can be set to FALSE in
- order to get more accurate classifications. Other accuracy problems
- still remains, but this time in the underlying point.in.polygon()
- function. There is no easy fix to this:
- <https://stat.ethz.ch/pipermail/r-help/2010-May/239035.html>
- No fix are planned in the close future to fix this error.
- Thanks to Wei Shangguan (see below) for pointing this 'bug'.
-
- 20100513 Added the ISSS (not to be confused with the 'Australian ISSS')
- texture triangle to the
- list of pre-defined texture triangles. Many thanks to Wei Shangguan,
- PhD from the School of geography of Beijing normal university
- for providing the code of the triangle.
-
- 20100416 Added the Canadian texture triangle to the list of pre-defined
- texture triangles.
-
- 20100409 Created an r-forge page for the package and uploaded it to SCM
- http://r-forge.r-project.org/scm/?group_id=740
-
- 20100409 Finished documenting the function TT.plot with inlinedocs. Package
- successfully compiled.
-
- 20091221 The parameter 'fg' is now defunct, and replaced by 'col' that accepts
- several values (while fg only accepts one). 'fg' still exists as an
- option, but shouldn't produce any effect.
-
- 20091119 Simplified some redundant code in TT.css2xy(), the function that
- transforms clay silt sand data into x-y coordinates.
-
- 20091118 Corrected a bug in the function TT.normalise.sum() (that couldn't
- handle data.frames)
-
- 20091014 Added the Belgian soil texture triangle to the list of pre-defined
- texture triangles (now 8).
-
- 20091013 The TT.mahalanobis() function can now compute a grid of the Mahalanobis
- distance on log-ratio trasnformation of soil texture data. New option
- alr, default = FALSE, can be set to TRUE for alr transformation.
-
- 20091013 Added TT.chemometrics.alr(), for additive log-ratio trasnformation of
- soil texture data. This is a copy of the alr() function in the chemometrics
- package, with minor modifications for soil texture data. Used internally
- in TT.mahalanobis().
-
- 20091011 Added TT.normalise.sum(), that normalise the sum of the 3 texture classes
- to text.sum (100%).
-
- 20091011 The options 'pow' and 'q.max.dist' are now set to 0.5 and 50 respectively.
- This is a stronger smoothing than the previous values.
-
- 20091011 TT.iwd() has now a 'q.max.dist' option user to determin 'max.dist' if this
- last is set to NULL. max.dist is the maximum euclidian distance, between
- a grid point and a data point. If the distance between the grid point and
- the data point is higher than max.dist, this point is not used to calculate
- the iwd value. max.dist default value is
- quantile( x = euclidian.distances, probs = q.max.dist )
-
- 20091011 The option value 'z.type = "map"' is now deprecated in TT.plot(). Replaced
- by TT.iwd() and TT.image(), called outside TT.plot().
-
- 20091011 TT.as.image() internal function deprecated. now inside TT.iwd()
-
- 20091011 TT.image.shade() internal function deprecated. now inside TT.iwd()
-
- 20091011 TT.iwd.image() renamed to TT.iwd(). The function now output a list with
- a x y grid and z value matrix, ready to be plotted by TT.image(). The
- function is not plotting the image any more.
-
- 20091011 TT.iwd() internal function is deprecated. The name will be attributed to
- TT.iwd.image()
-
- 20091010 TT.baseplot() now has a geo option.
-
- 20091010 TT.kde2d() function created. Wrapper for MASS function kde2d(), but
- customized for texture triangles. Results can be displayed by
- TT.contour(), TT.image(), contour() or image().
-
- 20091010 TT.image() function created. Wrapped for image(), but customized
- for texture triangles. Used to display x-y-z list data in the same
- format as 'x' in contour() or image().
-
- 20091010 TT.contour() function created. Wrapped for contour(), but customized
- for texture triangles. Used to display x-y-z list data in the same
- format as 'x' in contour() or image().
-
- 20091010 TT.mahalanobis() function created. Wrapper for the function mahalanobis(),
- but customized for texture triangles. Results can be displayed by
- TT.contour(), TT.image() [see above], contour() or image(). Calculates the
- Mahalanobis distance for 2 of the 3 texture classes, on a regular x-y grid,
- backtransformed into clay silt sand, used to calculate the Mahalanobis
- distance.
-
- 20091010 Added TT.xy.grid() that generates a regular grid on the
- x-y axis. Made after part of kde2d
-
- 20091009 Modified TT.plot() function so it accepts an optionnal 'geo' option and an
- 'add' option that behaves like plot(add=TRUE) when non-null. This is intended
- to allow overplotting a soil texture triangle over a background plotted by
- another function (i.e. heat map, contour map etc.)
-
- 20091009 Added TT.locator(). This function is equivalent to the locator() function,
- except that it returns clay silt sand coordinates instead.
-
- 20091009 Added TT.xy2css() a function to convert x-y coordinates into clay silt sand.
-
- 20091009 renamed TT.arrows() to TT.axis.arrows().
