Dear all:

I have six vector from six DIF detection results.
as below:
> difMH[[100]]$DIFitems
 [1]  1  9 19 21 22 24 25 27 29 30 34 38 40
> difMH[[90]]$DIFitems
 [1]  1  2  9 14 18 19 21 22 25 28 30 34 38 39
> difMH[[80]]$DIFitems
 [1]  1  8  9 19 21 22 24 25 26 28 30 34 38
> difMH[[70]]$DIFitems
 [1]  1  8  9 10 16 18 21 22 25 28 30 32 34 38 39
> difMH[[60]]$DIFitems
 [1]  1  9 19 21 22 23 25 27 30 34 36 38 39
> difMH[[50]]$DIFitems
 [1]  1  9 10 11 17 18 21 22 23 25 28 30 34 38 39

I have two questions.

first, how to combine these to a matrix?

second, how to compare them with "1 9 21 22 25 30 34 38"
how much units hit?
how much units are false-alarm?

thanks!
