Subject: tabout incorrect frequencies

Hi,

Whilst using tabout to create latex tables I noticed that some of the frequencies are incorrect. 

So a situation where I have such an issue is where a variable has all missing values. 

A small amount of background here; so in the example below I'm tabulating how aetiologies were identified, by bloods, biopsy or other. These are all bools, so either 0 or 1 (or missing). 
There are actually 5 patients that have blood = yes, and both AetHepC_biopsy and AetHepC_oth are completely missing. The tabulated frequencies correctly report the 5 bloods = yes but also report that there are 5 biopsies= yes and 5 others= yes when in fact they're both missing.  

Apologies for the long-winded explanation - has anyone else had this issue?

tabout  AetHepC AetHepC_blood AetHepC_biopsy AetHepC_oth using temp.tex, rep ///
                                                                                    c(freq col) f(0  0) clab(N %)   ///
                                                                                    style(tex) bt  font(bold)  wide(22)  ///
                                                                                    topstr(9cm) botstr(Temp data) one      



Best regards,

Richard
