This is my approach:
If "cosa" is your data.frame . e.g.
>cosa
i1 i2 dis
[1,] 1 1 0.00
[2,] 1 2 0.93
[3,] 1 3 0.80
[4,] 1 4 1.00
[5,] 2 2 0.00
[6,] 2 3 0.02
[7,] 2 4 0.22
[8,] 3 3 0.00
[9,] 3 4 0.95
[10,] 4 4 0.00
# first crate a square matrix of 0
I have a dissimilarity dataset with the form:
1 1 dissimilarity value
1 2 ...
1 3
1 4
2 2
2 3
2 4
...
I would like to do nonmetric multidimensional scaling with this data, but I
am having trouble using this format. I would like to either find a function
that accepts this format or find
2 matches
