data frame search
Hi,
I want to make a data frame which contains the positions of some searched values in another data frame.
Like:
Dataframe 1:
1 2 3 4 1 2 3 4
2 3 4 1 2 3 4 2
4 1 2 3 2 3 4 1
Let's say I searched on "4", then Dataframe 2 should contain:
x y
1 4
1 8
2 3
2 7
3 1
3 7
I have written a routine, but it seems to me that it isn't that perfect:
x<- 0
