[R] problem in matching numbers in two variables

[sagarnikam123]

i want to compare two variables (having numbers) serially for
matching/dismatching
both having equal length

> x
  [1] 2 2 1 2 3 2 2 2 2 3 3 2 2 2 2 2 2 3 2 2 2 2 2 2 2 2 2 2 3 2 3 2 2 2 1
2 2
 [38] 2 2 2 3 2 3 2 2 1 2 2 2 2 1 1 1 3 2 2 2 2 1 1 3 1 1 1 2 2 2 3 2 3 3 3

 [75] 2 2 3 2 2 1 1 1 2 3 2 2 2 2 2 2 2 2 2 1 1 3 2 2 2 2 2 2 2 2 2 2 2 1 3
> y
  [1] 2 2 2 1 3 1 3 2 1 3 3 3 3 2 2 1 2 3 3 3 1 1 2 2 2 2 2 2 1 2 3 1 2 2 1

> length(x)
[1] 109
> length(y)
[1] 109
> #both having equal length
> which(x%in%y)  #gives no of matches positions
  [1]   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15  16  17

 [73]  73  74  75  76  77  78  79  80  81  82  83  84  85  86  87  88  89

 [91]  91  92  93  94  95  96  97  98  99 100 101 102 103 104 105 106 107
108
[109] 109
> length(which(x%in%y))
[1] 109

it show that all numbers are matched ,but in real this is not true
so,how to find matched numbers from two variables(numeric) like this?
