st: selectvars and factor variables

[A Loumiotis <antonis.loumiotis@gmail.com>]

Hi,
I would like to use the package selectvars written by Nick Cox but my
variable list contains factor variables and selectvars does not allow
factor variables.  So I would like to substitute in my variable list
the factor variables with the dummy variables that "xi:" creates and
then run selectvars on my expanded variable list.  How can I do that?

For example:

local myvarlist var1 var2 i.var3 // where var3 is categorical with
four categories
local myevarlist var1 var2 Ivar3_2-4
selectvars `myevarlist', min(2) max(2)

My question is how to create myevarlist from myvarlist?

Thanks,

Antonis Loumiotis
