It might still be a matter of taste, but, for many codings I think michael.blasniks approach is very powerfull---at least for documentation. Also remember that you can create your dataset within the original do-file, if you don't want to split the documentation into different files: -----------------------mydofile.do use nation, clear <commands> sort nation // Create Origin-Variable preserve input nation origin 1 3 2 3 3 3 4 3 5 2 6 2 7 2 8 1 ... 141 10 end sort nation save origin, replace restore // Merge Origin Variable to nation-data merge nation using origin exit ---------------------------------------------- Adrian.P.Mander@gsk.com wrote: > OR just use a recode or is this missing the point? > > gen origin = natio > recode origin 3=7 8 12 69 139 141=10 14=8 ... etc > > cheers > Ade > > > > > "Michael Blasnik" > <michael.blasnik@verizon. > net> > To: > statalist@hsphsun2.harvard.edu Sent by: > owner-statalist@hsphsun2. cc: > harvard.edu Subject: st: Re: > multiple )))brackets, is there a more efficient way? > > > 25-May-2004 14:45 > Please respond to > statalist@hsphsun2.harvar > d.edu > > > > > > The suggestion to use inlist may be a step in the right direction, but if > you have a coding for every county in the world or any list with more than > a few dozen codings, I would think that you should create a dataset with > the > codings (often this coding information is available in a way that makes the > dataset creation fairly straightforward) and then use -merge- to bring them > in. > > sort nation > merge nation using nationcodes > > You can always list the nationcode file to document what the mapping is. > > Michael Blasnik > michael.blasnik@verizon.net > > ----- Original Message ----- > From: "Annelies Vos" <a.vos@erasmusmc.nl> > To: <statalist@hsphsun2.harvard.edu> > Sent: Tuesday, May 25, 2004 2:35 AM > Subject: st: multiple )))brackets, is there a more efficient way? > > > Dear all, > > in the FAQs I found the following very useful recommendation: > > instead of: > > . generate byte a = 1 if y <= 20 > > . replace a = 2 if y > 20 & y <= 30 > > . replace a = 3 if y > 30 & y <= 40 > > . replace a = 4 if y > 40 & y <. > > > > do the following: > > > > . #delim ; > > . generate byte a = > > cond(y<=20, 1, > > cond(y<=30, 2, > > cond(y<=40, 3, > > cond(y<., 4, > > . )))); > > > > However, the variable I want to use it for (nationality) has many > > values (every country in the world), which should be recoded into > > countrygroups.
