Hi all, I've got a project where I have to calculate weight-for-age Z-scores, preferably using the WHO standards.
WHO have been very nice to publish macros for doing this in both STATA,SPSS, SAS and Splus formats (see http://www.who.int/childgrowth/software/en/), but for some reason have chosen not to use the free R alternative to Splus. In the Splus zipfile there are nine datafiles with a "sdd" file ending, presumably data dumps from Splus 7.x. I've tried using restore.data from the foreign package, but that does not work (probably because the data is saved in the newer format). I'm considering trying to read in spss files and massaging them to fit to the format that the splus macro is expecting, but I'd prefer to be able to use the Splus files directly. Has anyone on the list tried using the WHO anthro macros with R, and can tell me how they did it? Alternatively, could some, very kind, person try and open the Splus files, and save them in a R-readable format? I would be extremely grateful for any help on this.
