Hi Sema, read.csv2 use ',' as the decimal separator. Since '.' is used in your file, everything becomes a character which in turn makes pam complain that what you pass to the function isn't numeric.
Use read.csv2("data.csv", dec = ".") and it should work. You can also use class(d) to check the class of the matrix before you pass it to pam(). See ?read.table for more options. There is a base function called 'data', so naming a variable data is a poor choice.
