Hi Chris, This is a very rough first conceptual program you could use --
double check all the syntax as I know it won't work at first go. It's
untested but can be jiggered to work! Good luck! Anders
Use unique() to get your unique combinations, then loop or vectorize
through each unique
One way is to use the following functions:
?unique
?aggregate
?merge
For example,
x.df - data.frame(Group=LETTERS[c(1, 1, 1, 2, 3)], Value=c(1, 1, 2, 2,
0))
x.agg - aggregate(x$Value, list(Group=x$Group),
function(x){length(unique(x))})
x.agg
Group x
1 A 2
2 B 1
3 C 1
x.merged -
