Juli 2010 16:55 An: statalist@hsphsun2.harvard.edu Betreff: Re: AW: st: AW: Reshaping a Dataset This is a dataset that I received in Excel from an engineer in another section of our office. The data are airborne concentrations measured at several sites over several dates. The data set covers the period 2005 - 2009. There are over 500 lines of data, and the thought of having to rearrange these manually is, well, very unpleasant. reg -----Original Message----- >From: Martin Weiss <martin.weiss1@gmx.de> >Sent: Jul 23, 2010 10:32 AM >To: statalist@hsphsun2.harvard.edu >Subject: AW: st: AW: Reshaping a Dataset > > ><> > > >Begs the question: How come the data are organized in this fashion?
