Hi,
I have a list of data, e.g. r[[i]]
r[[1]]=
1 2
1 6
5 5
5.5 3
r[[2]]=
4 6
3 5
7 8
3 5
…
r[[500]].
In the first column, the selected values should like this:
(the later value)-(the former value)>=1
In the second column, the selected values should like this:
(the former value)-(the later value)>=1.
The outputs are:
For r[[1]]
[1,1] 1, [3,1] 5,
[1,2] 2
For r[[2]]
[1,1] 4, [3,1] 7
[1,2] 6, [2,1] 5
…
r[[500]].
I have no idea what kind of functions can be used in this process. Could you
help me? Thank you very much.
