Hello,
I doubt your Inf is a string, R does have the numeric value Inf (and
-Inf), just try 1/0.
As for the question,
x <- matrix(1:9, ncol = 3)
diag(x) <- 1/0
x
x[x == Inf] <- 0
x
Note that it could also be diag(x) <- 0
Hope this helps,

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 can do this by putting it into Excel, replacing and putting it back
into R but it's tedious, and I am sure there is a simple way to do it
in R.
If you have the route to do this, it would be much appreciated.
Best wishes
Nick Duncan
