There's a bit of formatting damage there, is this a matrix with rownames 1995:2003 and colnames 2:10? Have a look at this: m <- matrix(NA,9,9) m[,1] <- round(1e4*runif(9)) m[1,] <- round(1e4*runif(9)) colnames(m) <- 2:10 rownames(m) <- 1995:2003 m # should look like yours now m[-1,-1] <- 1:64 m -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
