Re: [R] for loop query

: 26 is i + (1 : 26) as the vector 1 :26 is calculated first what happens is that for i = 1 j goes over 2 : 27, with i = 2 over 3 : 28, ... what you want is (i + 1) : 26: for (i in 1 : 25) for (j in (i + 1) : 26) cat (i, j, "\n") HTH Claudia -- Claudia Beleites Dip

Re: [R] 1-Pearson's R Distance

the proxy package, but the calculation it straightforward (though a bit wasteful I suspect: first the whole matrix is produced, and as.dist cuts it down again to a triangular matrix): as.dist (0.5 - cor (t(x) / 2)) Take care wheter you want to use x or t(x). HTH Claudia -- Claudia Beleites Dip
