<p class="MsoNormal">Hello<br>
<br>
Please apologise if this is off-list.<br>
<br>
Today, a commercial company asked about numerical code and recent numerical code changes that routines of my R-package are based upon. The code is self-developed (by Carlo Albert) and based upon an algorithm to be published in a scientific article within the
next 4 weeks. I wonder (or doubt?) if the license (GPL-2) and the open source spirit would be fully regarded by the company. What is your recommendation to react on such a request? Is there sort of a standard text to send?<br>
<br>
Thanks for your help<br>
Sören<br>
