RE: st: --estimates table, drop()" and FACTOR variables (texdoc)

Hello all,
Carsten: thanks for your reply.
With 300 categories for
the factor variable, spelling each category out is rather daunting. My
quick workaround is to --estimate table, keep()-- the coefficients I
want as it results in shorter list.
And I thought factor variables were first-class citizens. Please do reply if there is a way to use factor variables in their new syntax with --estimates table--

you have to specify which factor variable you want to drop.
Look at this example:
sysuse auto, clear
reg price mpg i.rep78
est table, drop(2.rep78)
est table, drop(2.rep78 3.rep78)
best, carsten

Hello all,
I run a few specifications then try to drop a factor variable (~300 dummies) but --estimates table-- throws an error. Am I doing something wrong? If there is an issue with factor variables, is there a known workaround?
estimates table a1 a2 a3 a4 a5, drop(i.hsacode)
coefficient i.hsacode does not occur in any of the models
r(198);
. estimates table a1 a2 a3 a4 a5, drop(hsacode)
coefficient hsacode does not occur in any of the models
r(198);
. estimates table a1 a2 a3 a4 a5, drop(_hsacode)
coefficient _hsacode does not occur in any of the models
r(198);
BTW, I am using these --estimates table-- within a --texdoc stlog-- block.
