Bert,

dat1<-structure(list(SameName = 1:6, Individual = c(4L, 15L, 1L, 15L, 
2L, 4L), Age = c(80L, 56L, 75L, 56L, 58L, 80L), Gender = c("M", 
"F", "F", "F", "F", "M")), .Names = c("SameName", "Individual", 
"Age", "Gender"), class = "data.frame", row.names = c(NA, -6L
))
Your solution gives:

 dat1[!duplicated(dat1$Individual),]
#  SameName Individual Age Gender
#1        1          4  80      M
#2        2         15  56      F
#3        3          1  75      F
#5        5          2  58      F

The OP asked for:
And I want to pull out paired samples, so the resulting file would look something like this:
>>> SampleName Individual Age Gender
#>>> 1 4 80 M
>>> 2 15 56 F
>>> 4 15 56 F
>>> 6 4 80 M

Anyway, the question was not clear as I mentioned in the earlier mail.
Regards,
A.K.

Sorry. Typo. Corrected version  is:

yourframe[!duplicated(yourframe$Individual),]
