Replacing string in matrix with zero
Dear Rolf, You are of course quite right, however I wish the diagonal to be ignored by setting the value to zero. The inf was just recognising the flow value from self to self. A very fair point though. Best, Nick

Dear All, I have a matrix in which the diagonal has the string "Inf" in it. In order to be able to do cluster analysis this needs to be replaced with a Zero.
I am very sceptical about this assertion. "Inf" means infinity
which is of course *NOT* the same as 0. By anyone's standards.
I know nothing about cluster analysis, so I may be toadally out
to lunch in this, but I suspect that you need to re-think.
cheers,
Rolf Turner
