by creating the factor with the levels in the order you want:

 > test <- c(120402, 120402, 120402, 1323, 1323,200393, 200393, 200393, 
200393, 200393)
 > summary(factor(test, levels=unique(test)))
120402   1323 200393
      3      2      5

Hi
The result of a summary(as.factor(x)) (see example below) call is sorted 
according to the factor level. How can I get the result not sorted but 
in the original order of the levels in x?


 > test <- c(120402, 120402, 120402, 1323, 1323,200393, 200393, 200393, 
200393, 200393)
 > summary(as.factor(test))
   1323 120402 200393
      2      3      5

I need:
120402 1323 200393
      3    2      5

thanks for a hint

Use the levels argument of ?factor.

summary(factor(test, levels = unique(test)))
