Ok, I have solved one of my two questions myself by:
x = length(v1)length(unique(v1))
Now only one question remains, how can I find out which numbers were not unique in the rowvector v1?
Thanks.

Therefore, most values (out of the range of 1 to 13000) will not be present in the vector, some values will be unique, but other values are present multiple times. I am not really interested in the values that occur only once in the vector, but I do want to know which values occur more than once and also how many times these values occur.
