computing the average of variables with missing values in Stata -

-

i know how calculate avarage of variables without missing value, not sure calculating missing values. example have 6 area halls follows:

area_hall_1 area_hall_2 area_hall_3 area_hall_4 area_hall_5 area_hall_6 580         580         650         .           .           . 1000        1000        .           .           .            825         825         .           .           .           . 912         912         .           .           .           . 670         .           .           .           .           . 790         .           .           .           .           . 750         900         1000        1000        900     750

the reported (or rather implied) problem makes no sense whatsoever. consider data posted (an missing value needed in second observation). 

. clear  . input area_hall_1 area_hall_2 area_hall_3 area_hall_4 area_hall_5 area_hall_6       area_ha~1  area_ha~2  area_ha~3  area_ha~4  area_ha~5  area_ha~6  1. 580         580         650         .           .           .  2. 1000        1000        .           .           .           .   3. 825         825         .           .           .           .  4. 912         912         .           .           .           .  5. 670         .           .           .           .           .  6. 790         .           .           .           .           .  7. 750         900         1000        1000        900     750  8. end   . egen area_hall_mean = rowmean(area_hall_?)   . egen area_hall_count = rownonmiss(area_hall_?)   . l *_mean *_count , sep(0)        +---------------------+      | area_h~n   area_h~t |      |---------------------|   1. | 603.3333          3 |   2. |     1000          2 |   3. |      825          2 |   4. |      912          2 |   5. |      670          1 |   6. |      790          1 |   7. | 883.3333          6 |      +---------------------+   . di (580+580+650)/3  603.33333

the egen function rowmean() ignores missing values. how otherwise? other possibility report mean cannot calculated because there missing values. defensible, not @ typical stata style. means reported op wants. independent calculation display shows means reported desired. (a profound sceptic @ liberty inspect code viewsource _growmean.ado.)
