Hi Stefan,
How about this:
sddf<-read.table(text="age x
45 1
45 2
46 1
47 3
47 3",
header=TRUE)
library(prettyR)
sdtab<-xtab(age~x,sddf)
sdtab$counts

Thank you, this is already very helpful.
But how do I get it in the form
age var_x=1 var_x=2 var_x=3
45 1 1 0
46 1 00
So it would be a data frame with 4 variables.
Cheers!

You didn't say how you wanted to use it as a data.frame, but here is one way
d <- data.frame(
check.names = FALSE,
age = c(45L, 45L, 46L, 47L, 47L),
x = c(1L, 2L, 1L, 3L, 3L))
with(d, as.data.frame(table(age,x)))
which gives:
age x Freq
1 45 11
2 46 11
3 47 10
4 45 2
well, if I think about, its actually a simple frequency table grouped
by age. but it should be usable a matrix or data frame.

Dear All,
I have a seemingly standard problem to which I somehow I do not find
a simple solution. I have individual level data where x is a
categorical variable with 3 categories which I would like to aggregate
by age.
age x
45 1
45 2
46 1
47 3
47 3
and so on.
It should after transfo
6 matches
