## problem in matching numbers in two variables

 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 2 2  [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 1 2  [38] 1 2 3 2 1 3 1 1 2 2 2 2 1 2 1 2 3 2 3 2 1 2 2 3 1 1 1 2 2 2 3 2 3 3 3 3 3  [75] 2 2 1 2 1 2 1 2 1 3 3 3 1 2 2 2 1 2 1 2 2 3 2 3 2 3 2 2 2 2 1 2 2 2 3 > 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?

 Hello, Why not == ? x == y which(x == y) Hope this helps, Rui Barradas

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 ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.

 In reply to this post by sagarnikam123 I think this works bu there probably is a better way. xy  <- x %% y which(xy != 0) John Kane Kingston ON Canada > -----Original Message----- > From: [hidden email] > Sent: Sat, 28 Apr 2012 08:28:39 -0700 (PDT) > To: [hidden email] > Subject: [R] problem in matching numbers in two variables > > 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 > 2 2 >  [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 > 1 2 >  [38] 1 2 3 2 1 3 1 1 2 2 2 2 1 2 1 2 3 2 3 2 1 2 2 3 1 1 1 2 2 2 3 2 3 3 > 3 > 3 3 >  [75] 2 2 1 2 1 2 1 2 1 3 3 3 1 2 2 2 1 2 1 2 2 3 2 3 2 3 2 2 2 2 1 2 2 2 > 3 >> 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? > > -- > View this message in context: > http://r.789695.n4.nabble.com/problem-in-matching-numbers-in-two-variables-tp4594912p4594912.html> Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > [hidden email] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help> PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html> and provide commented, minimal, self-contained, reproducible code. ____________________________________________________________ GET FREE SMILEYS FOR YOUR IM & EMAIL - Learn more at http://www.inbox.com/smileysWorks with AIM®, MSN® Messenger, Yahoo!® Messenger, ICQ®, Google Talk™ and most webmails ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.

 No its not perfectly working see below > j<-c(1,1,2,2,3) > k<-c(2,1,1,1,1) > j%%k [1] 1 0 0 0 0 problem comes when one of my sequence have 1 Sagar Nikam B.Pharm, M.Sc(Bioinformatics) Software Engineer (Data Research Analyst ) Trendwise Analytics,Bangalore India

## Re: problem in matching numbers in two variables

 I think I misread the question.  Is this what you want j <- c(1,1,2,2,3) k <- c(2,1,1,1,1) xx  <- j == k which(xx == TRUE) John Kane Kingston ON Canada > -----Original Message----- > From: [hidden email] > Sent: Sat, 28 Apr 2012 23:48:43 -0700 (PDT) > To: [hidden email] > Subject: Re: [R] problem in matching numbers in two variables > > No its not perfectly working see below > >> j<-c(1,1,2,2,3) >> k<-c(2,1,1,1,1) >> j%%k > [1] 1 0 0 0 0 > > problem comes when one of my sequence have 1 > > -- > View this message in context: > http://r.789695.n4.nabble.com/problem-in-matching-numbers-in-two-variables-tp4594912p4595849.html> Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > [hidden email] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help> PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html> and provide commented, minimal, self-contained, reproducible code. ____________________________________________________________ FREE 3D MARINE AQUARIUM SCREENSAVER - Watch dolphins, sharks & orcas on your desktop! ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.
