Re: [R] Triangular matrix upper to down

Ok, thanks this solution test[lower.tri(test)] <- t(test)[lower.tri(test)] works perfectly well :) Thanks Best marcin M. -- View this message in context: http://r.789695.n4.nabble.com/Triangular-matrix-upper-to-down-tp3845107p3845352.html Sent from the R help mailing list archive at Nabble

Re: [R] Triangular matrix upper to down

Mhy, I think that this solution It doesn't work with odd dimension. Suppose we have a reference matrix 13x13 (near i present a table format i.e save by write.table). This matrix name a response2. "V1" "V2" "V3" "V4" "V5" "V6" "V7" "V8" "V9" "V10" "V11" "V12" "V13" "1" 0 1.4142135623731 1 1.732050
