 +==== library (twinspanR) ====
 +I created an experimental R library ''​twinspanR''​ with the TWINSPAN algorithm - you may install it from GitHub repository https://​github.com/​zdealveindy/​twinspanR (note: this library is currently in beta stage under development,​ and some parts may not be functional). To install any library from GitHub, you will need to first install the package ''​devtools''​ written by Hadley Wickham, which contains a set of tools for development of R packages. After installing ''​devtools'',​ use the function ''​install_github''​. Note that the use of the library has some limitations:​ it can be installed only on Windows platform (since the engine of the library is based on running *.exe file externally) and you need a permanent access to the folder where the library is installed (usually in Program Files/​R/​R-x.x.x/​library,​ but could be also in some other personalized place). Without the access to this folder the function ''​twinspan''​ cannot run correctly.

 +How to install: follow instructions at https://​github.com/​zdealveindy/​twinspanR ​
