Looks like a matrix (which is, I guess, a type of array). To sort by the first column, try acc.gp.bl.wtmn[order(acc.gp.bl.wtmn[,1],] >>acc.gp.bl.wtmn > Gp17 Gp4 >1 0.5703125 0.6406250 >10 0.7812500 0.7109375 >11 0.8046875 0.7343750 >12 0.8359375 0.7890625 >13 0.8515625 0.7109375 >14 0.8281250 0.7343750 >15 0.8671875 0.7812500 >16 0.8125000 0.7578125 >17 0.7734375 0.7500000 >18 0.8000000 0.7800000 >19 0.8700000 0.7300000 >2 0.8046875 0.7265625 >20 0.8300000 0.7400000 >21 0.7500000 0.8000000 >22 0.7700000 0.7600000 >23 0.8200000 0.7800000 >24 0.7600000 0.7400000 >25 0.8100000 0.8000000 >3 0.7578125 0.7812500 >4 0.8203125 0.7890625 >5 0.7890625 0.7421875 >6 0.7265625 0.7812500 >7 0.8125000 0.7421875 >8 0.8515625 0.7265625 >9 0.8203125 0.6953125 > >My question is: How do I sort by the first index (the values are 1:25) >without losing the associated values per index value for the two >columns(Gp17 and Gp4).
