Re: st: generate stata variables in mata and set the names from matrices

I changed the line below

stata(`"local namer=radian[1,rd]"')

to

stata(`"global namer=radian[1,rd]"')

but it still doesn't work as I want... Line by line entry works this way as well. (by the way, there must be a shorter way to code what I want like 3 lines shorter but how)

I want to generate stata variables in mata, and set the names of those
variables using a mata matrix. I use the code below which is supposed to
work -it works when I enter the lines line by line-, but then when I run it
in a do file, it doesn't work. It doesn't generate a HHI_R50 variable. It
generates a HHI_R variable with no extension referring to the corresponding
matrix value. What's wrong?

...
mata
...
radian=(50,75,200)
  for (rd=1; rd<=cols(radian); rd++) {
...
        st_matrix("radian", radian)
        st_numscalar("rd", rd)
        stata(`"local namer=radian[1,rd]"')
        stata("gen HHI_R`namer'=.")
        st_store(., "HHI_R`namer'", HHI_R)
}
end
...
