Hi Peter,
Thanks a lot for the answers. I can see that I need to read about outer().
However I get a different result than expected.
R> x <- scan("digits.txt")
Read 220000 items
R> head(x)
[1] 0 10097 32533 76520 13586 34673
R> x <- x[-seq(1,220000,11)]
R> head(x)
[1] 10097 32533 76520 13586 34673 54876
R> head(c(outer(x,10^(0:4), "%/%")) %% 10, 10) #
[1] 7 3 0 6 3 6 9 7 2 5
Regards
Martin
