the dates into numbers of days (see <a href="http://stackoverflow.com/questions/19564930/how-do-i-convert-date-to-number-of-days-in-r">

<pre style="word-break:break-all"><span style="font-family:"Lucida Console";background:#E1E2E5">I guess my question is typically the one of a begginer on Traminer. I've been collecting a list of stays that some people did in a hospital. The beginning and end dates of each stay are rather precise (dd/mm/yyyy) and I'd like to stick to that precision for the moment. Although, in the user's guide and the Traminer's mailing list I couldn't find any example where the beginning and the end of the spell are written in a date format (not just as a year).<o:p></o:p></span></pre>
