[R] pulling out pairs from data frame

[arun]

Hi,
The question is not clear so not sure this is what you wanted.

dat1<- read.table(text="
SameName  Individual  Age Gender
1 4  80  M  
2 15  56 F
3 1 75  F
4 15  56  F
5  2  58  F
6 4  80  M
",sep="",header=TRUE,stringsAsFactors=FALSE)
reps<-c(4,15) 

 dat1$Newcol<-as.numeric(dat1$Individual%in% reps)
 dat1
#  SameName Individual Age Gender Newcol
#1        1          4  80      M      1
#2        2         15  56      F      1
#3        3          1  75      F      0
#4        4         15  56      F      1
#5        5          2  58      F      0
#6        6          4  80      M      1
A.K.

Subject: [R] pulling out pairs from data frame

Hello everyone, 
I'm having trouble pulling out paired samples from a data set... I have the following:

reps<-c(4,15) #the variable reps is a list of all paired samples
>data





  
  SameName
  
  
  Individual
  
  
  Age 
  
  
  Gender
  


  
  1
  
  
  4
  
  
  80
  
  
  M
  


  
  2
  
  
  15
  
  
  56
  
  
  F
  


  
  3
  
  
  1
  
  
  75
  
  
  F
  


  
  4
  
  
  15
  
  
  56
  
  
  F
  


  
  5
  
  
  2
  
  
  58
  
  
  F
  


  
  6
  
  
  4
  
  
  80
  
  
  M
  




I'd like to make a new variable with only the samples that have pairs. Any suggestions would be greatly appreciated

Thanks!
