yes, your solution is working fine with a little tweaking of the vector

position of labels around respective points;

Is it possible ?
Otherwise, how can I do, according to you ?

exactly what is

Anyway, you can save yourself a lot headache, if you start using lists for your

Lists can be used easily in cycles.
for (i in 1:n) {
some.list[i] - some.function(some.other.list[i])
}
and also lapply/sapply functions can be useful

It is always useful to look at the data in multiple ways. The unique()
function will remove the duplicates in your data so that isoMDS will work:
set.seed(42)
x - matrix(sample(0:1, 20, replace=TRUE), 10, 2)
x
[,1] [,2]
[1,]10
[2,]11
[3,]01
[4,]10
Spearman would be easier since you just convert the data to ranks and use
the Pearson correlation:
set.seed(42)
x - data.frame(matrix(sample(1:9, 20, replace=TRUE), 10, 2))
x
X1 X2
1 9 5
2 9 7
