Did you mean:
x1g2_1

Index and dummy
...the group and equal to 0, otherwise.
What I have done was:
id=(6000)
x1sort=sort(x1, decreasing=TRUE)
x1g8_1=x1sort[1:750]
x1g8_2=x1sort[751:1500]
x1g8_3=x1sort[1501:2250]
x1g8_4=x1sort[2251:3000]
x1g8_5=x1sort[3001:3750]
x1g8_6=x1sort[3751:4500]
x1g8_7=x1sort[4501:5250]
x1g8_8=x1sort[5251:6000]
x1g4_1=c(x1g8_1, x1g8_2)
x1g4_2=c(x1g8_3, x1g8_4)
x1g4_3=c(x1g8_5, x1g8_6)
x1g4_4=c(x1g8_7, x1g8_8)
x1g2_1=c(x1g4_1, x1g4_2)
x1g2_2=c(x1g4_3, x1g4_4)
x1ng=c(x1g2_1, x1g2_2)
After this I did the dummy vector (the example is for group4)
dum= replace(matrix(0, 4, 1), cbind(4, 1), 0)...
