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

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 18 [19] 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 [37] 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 [55] 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 [73] 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 [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?
Please use dput() in future. It's not quite clear what you exactly want but maybe this will do x == y which(x==y) Berend
