st: -labgen- available from SSC |

Thanks to Kit Baum, a new package -labgen- is now downloadable from SSC. -labgen- requires Stata 8. It contains two commands, to generate or replace variables with definitions copied to variable labels. There is more after my signature. Nick n.j.cox@durham.ac.uk -labgen- generates a new variable using -generate-, except that the definition of the variable, i.e. whatever follows the equals sign, including any -if- or -in- qualifiers specified, becomes the variable label. -labreplace- replaces an existing variable using -replace-, except that the definition of the variable, i.e. whatever follows the equals sign, including any -if- or -in-qualifiers specified, becomes the variable label. Thus labgen logy = ln(y) creates a new variable -logy- with variable label "ln(y)". Similarly labreplace logy = ln(y) if foo > 2 replaces variable -lny- with a new variable label "ln(y) if foo > 2". A first version of -labgen- was posted by Paul Lin, then working for what is now StataCorp, to Statalist on 16 July 1996. I posted a revision on 18 July 1996. At this distance I cannot trace what the difference was. Alan H. Feiveson drew my attention to -labgen- once more in Statalist postings on 25 September 2008 and persuaded me publicly to resuscitate it. He deserves much of any credit and a small fraction of any blame that you may deem deserved for its re-publication. -labgen- as published on SSC is rewritten and -labreplace- is new as of 13 October 2008. The help carries more details as usual. For other commands in similar spirit, search -genl- and see Weesie (1997), or search -defv- and see Gleason (1997, 1999).
