Subtracting elements of a vector from each other stepwise

Hi,
Not sure this is what you wanted:

?sapply(seq_along(x), function(i) {x1<- x[i]; x2<- x[-i];

#???? [,1] [,2] [,3] [,4]
#[1,]?? 17?? 19?? 23?? 29
#[2,]?? 19?? 17?? 19?? 23
A.K.

Subject: [R] Subtracting elements of a vector from each other stepwise

I am trying to figure out how to create a loop that will take the
difference of each member of a vector from each other and also spit out
which one has the least difference.

I do not want the vector member to subtract from itself or it must be able
to disregard the 0 obtained from subtracting from itself.

For example:

x = c(17,19,23,29)
