st: about centile and r(c_#)

hi all,
I'm lit bit confused by centile. for example
************************
.clear
.sysuse auto
. centile price, c(30 60)
-- Binom. Interp. --
Variable | Obs Percentile Centile [95% Conf. Interval]
-------------+-------------------------------------------------------------
price | 74 30 4424.5 4110.565 4679.134
| 60 5705 4912.708 6232.007
*************************
then I want to know the values of centiles, say
*****************************
. di r(c_30)
*****************************
I get missing values.
while
**************************
. di $S_7
4424.5
**********************
so, why r(c_30) doesn't work and why $S_7 works?
thanks,
Guang
