I have two numerical vectors; hun2 is a subset of hun1:

> hun1
  [1] 147 198 141 170 184 136 150 134 144 161 124 103 107 110 121 79 106 51
[19] 102 109 52 71 52 80 95 78 75 96 101 107 107 80 71 49 71
64
[37] 58 68 75 85 55 52 70 90 98 90 100 98 74 78 60 69 106

[55] 106 124 111 97 66 83 54 58 74 76 73 101 68 50 45 69 69

[73] 80 55 79 58 61 72 90 91 99 58 63 57 72 36 58 44 63

[91] 39 41 48 65 86 73 74 69 66 59 52 68 91 100 151 112 119

[109] 66 73 87 99 79 109 94 80 63 51 46 39 28 34 49 45 36 32

[145] 47 34 42 45 50 48 49 55 62 46 61 60 42 48 58 49 60

>hun2
[1] 151 112 119 93 66 73 87 99 79 109 94 80 63 51 46 39 28 34
49
[20] 45 36 32 36 39 52 63 59 47 57 52 46 39 54 53 80 43 48 37
[39] 42 43 47 34 42 45 50 48 49 55 62 46 61 60 42 48 58 49 60

i want to cbind hun1 to hun2 at the position where they match.

i have attempted to start this by using pmatch() to identify where it is they match- i get the following results.

> pmatch(hun1,hun2,duplicates.ok=TRUE)
  [1] NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA 9 NA 14 NA 10 25 NA 25 12 NA
[26] NA NA NA NA NA NA 12 NA 19 NA NA 55 NA NA NA 48 25 NA NA NA NA NA NA
NA NA
[51] 52 NA NA NA NA NA NA NA 5 NA 33 55 NA NA 6 NA NA 45 20 NA NA NA 12
48 9
[76] 55 51 NA NA NA 8 55 13 29 NA 21 55 NA 13 33 16 NA 37 NA NA 6 NA NA
5 27
[101] 25 NA NA NA 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
[126] 22 21 16 25 13 27 28 29 25 15 16 33 34 12 36 37 38 39 36 28 18 39 20 45 37
[151] 19 48 49 15 51 52 39 37 55 19 52

is there anyway that i can specify pmatch() to work if and only if it identifies all of hun2: something like this???   [1] NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
