functions for high dimensional integral
...ompute a high dimensional integral. Currently I'm using the
function adapt in R package adapt. But this method is kind of slow to me.
I'm wondering if there are other solutions. Thanks.

Subsetting to unique values
I want to take the first row of each unique ID value from a data frame.
For instance
> ddTable <-
data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry"))
I want a dataset that is
Id Name
1 Paul
2 Bob
> unique(ddTable)
Will give me all 4 rows, and
> unique(ddTable$Id)
Will give me c(1,2), but not accompanied by the name column.
