[R] Why CLARA clustering method does not give the same classes as when I do clustering manually?

[ABABAEI, Behnam]

Hi,


I am using CLARA (in 'cluster' package). This method is supposed to assign each observation to the closest 'medoid'. But when I calculate the distance of medoids and observations manually and assign them manually, the results are slightly different (1-2 percent of occurrence probability). Does anyone know how clara calculates dissimilarities and why I get different clustering results?
