[R] How to find the non matching vectors among these five, if so how we can find the non matching element of that vectors?

[arun]

Hi,
Try this:


list1<-list(a=a,b=b,c=c,d=d,e=e)
dat1<-as.matrix(do.call(rbind,lapply(list1,`[`,1:4)))
dat1[duplicated(dat1)|duplicated(dat1,fromLast=TRUE),]
  [,1] [,2] [,3] [,4]
#a    1    2    3   NA
#c    1    2    3   NA
#d    1    2    3   NA

dat1[!(duplicated(dat1)|duplicated(dat1,fromLast=TRUE)),]
  #[,1] [,2] [,3] [,4]
#b    1    2    3    4
#e    1    4    5   NA

which(!(duplicated(dat1)|duplicated(dat1,fromLast=TRUE)))
#[1] 2 5


dat2<-dat1[!(duplicated(dat1)|duplicated(dat1,fromLast=TRUE)),]

 do.call(rbind,apply(dat2,2,function(x)x[!(duplicated(x)|duplicated(x,fromLast=TRUE))]))
     b  e
#[1,] 2  4
#[2,] 3  5
#[3,] 4 NA
A.K.

Hello,

Say all the below five vectors should have same elements in any situation.
How to find the non matching vectors among these five, if so how we can find the non matching elements of those vectors?
Can anyone help?

a=c(1,2,3)
b=c(1,2,3,4)
c=c(1,2,3)
d=c(1,2,3)
e=c(1,4,5)
identical(a,b,c,d,e)
