-<h2><span class="spip_out">Other works and softwares on soil textures
-(triangles)</span></h2>
-<p class="spip">Numerous other works and softwares exist that deal with
-soil textures and soil textures triangles. Nevertheless, to my
-knowledge, <strong class="spip">The Soil Texture Wizard is the only
-tool that offers an integrated set of functionalities for soil textures
-(smart graphs + classification + multi-triangle + multi-geometry)</strong>.</p>
-<h3><strong class="spip">Ternary graphs (without soil textures classes)</strong>:</h3>
-<strong class="spip">triangle.plot()</strong> and <strong class="spip">triangle.biplot()</strong>
-functions, from the <strong class="spip">R package <a href="http://cran.univ-lyon1.fr/web/packages/ade4/index.html" class="spip_out">ADE4</a></strong>, by Daniel Chessel, Anne-Beatrice
-Dufour and Stephane Dray. These functions are not specialised in soil
-textures plots (and can not plot soil texture classes), but offer of
-nice "<strong class="spip">zoom</strong>" feature that dont exist in
-The Soil Texture Wizard, nor in the PLOTRIX package (see below). For
-illustrations, see the <a href="http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=34" class="spip_out">web-page on triangle.plot() on the R Graph Gallery,

-<h3><strong class="spip">Ternary graphs (with soil textures classes)</strong>:</h3>
-The functions <strong class="spip">soil.texture()</strong> and <strong class="spip">soil.texture.uk()</strong> from the <strong class="spip">R
-package <a href="http://cran.r-project.org/web/packages/plotrix/index.html" class="spip_out">PLOTRIX</a></strong>, by Jim Lemon <i class="spip">et
-al</i>. It allows to create graphs, with or without soil textures data,
-following the <strong class="spip">USDA</strong> or the <strong class="spip">UK</strong> soil texture triangles. There is also an
-underlying ternary plot function that can be used without soil texture
-classes. It is nevertheless not possible to project the triangles into
-another geometry, nor to transform or classify soil textures data. <strong class="spip">The R functions presented here ("The Soil Texture
-Wizard") are originally (i.e. 3 years ago) derived from some functions
-of the PLOTRIX package</strong>. Now, there probably not a single
-common line of code, and the 2 set of functions are unfortunately not
-compatible. But The Soil Texture Wizard obviously wouldnt exist if I
-havent been able to freely adapt the code from PLOTRIX (reason why
-free and open-source licences are so great). For illustrations of
-PLOTRIX, see the <a href="http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=76" class="spip_out">web-page on soil.texture() on the R Graph Gallery, by

+Introduction    <a id="intro"></a>
+------------
+
+`soiltexture` is a [package][R_packages] (_extension_) for 
+the [R][], a _free software environment for statistical_ 
+_computing and graphics_.
+
+`soiltexture` is a toolbox for plotting, classifying and 
+transforming [soil texture][soil_texture] data (clay, 
+silt and sand contents).
+
+Soil texture data and soil [texture classifications systems][texture_classif] 
+are traditionally visualised (plotted) on [ternary diagrams][ternary_plot]  
+(called texture plots, texture diagrams or texture triangles).
+
+`soiltexture` currently implements 17 soil texture classification 
+systems from all around the world. See [here][triangle_gallery] 
+for a gallery of available texture triangles, and see also 
+the package vignette (_after [installing](#installation)_ 
+_the package_):
+
+    vignette( "soiltexture_vignette" )

+
+
+Installation    <a id="installation"></a>
+============
+
+Install R
+---------
+
+You need to install beforehand the sofware [R][] ("_a free_ 
+_software environment for statistical computing and graphics_").
+
+From R homepage, go to the [CRAN homepage][CRAN] or (_better_) choose 
+the nearest [CRAN mirror][CRAN_mirrors].
+
+From there, choose 'Download R for ...' (Windows, Mac or Linux), 
+and then choose 'base' or 'install R for the First time'.
+
+From there (latest stable R release), download the software 
+installation files (if you are running on Windows) and install 
+the program on your computer (follow the instructions from the 
+installer). 
+
+Note: Unless you know what you are doing, it is recommended 
+to install the latest R release (it may not always be possible 
+to install the package `soiltexture` on older versions of R, 
+or some of the latest features might be missing).
+
+
+
+Install soiltexture (stable release)
+------------------------------------
+
+Open R, and type the command:
+
+    install.packages( "soiltexture" ) 
+
+
+
+Install soiltexture (development version)
+-----------------------------------------
+
+Note: This will only work with the latest (stable) version 
+of R. You should also check on the package R-forge page 
+(here: http://r-forge.r-project.org/R/?group_id=740) that 
+the "Build status" of `soiltexture` is "Current" (and not 
+"Failed to build").
+
+Open R, and type the command:
+
+     install.packages("soiltexture", repos="http://R-Forge.R-project.org") 
+
+
+
+Text based graphical user interface    <a id="text_gui"></a>
+===================================
+
+From version `1.3.0` the package soil texture comes along 
+with a simple [text-based graphical user interface][text_gui]. 
+
+After you have [installed](#installation) `R` and the package 
+`soiltexture`, simply start R and type:
+
+    soiltexture::soiltexture_gui()
+
+This will start the text-based graphical user interface. You 
+will be asked a series of simple question (4 to 8. With a list 
+of possible answers), to import soil texture data, visualise 
+it on a texture triangle and classify the texture data according 
+to a classification system. Without typing any other commands 
+than the one above. You can also display an empty texture 
+triangle (without data-points) and/or display a texture triangle 
+without classification system.
+
+More information on how to prepare your soil texture data 
+can be found on the function help page. In R, type:
+
+    help( "soiltexture_gui" )
+
+or simply
+
+    ?soiltexture_gui
+
+Note: An alternative way to call `soiltexture_gui` is to type:
+
+    library( "soiltexture" ) 
+    soiltexture_gui()
+
