Re: [R] SORTING Arrays by index value
This should do it: > acc.gp.bl.wtmn[order(as.numeric(row.names(acc.gp.bl.wtmn))),] (This is not completely straightforward because in a dataframe, row names are almost always stored as character vectors, which means that you need to convert the row names to numeric values before calling order()) -- Tony Plate At Tuesday 11:46 AM 2/4/2003 -0500, Mark G Orr wrote: Hello, I'm somewhat new to R.

Here is the array 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 0.750 >18 0.800 0.780 >19 0.870 0.730 >2 0.8046875 0.7265625 >20 0.830 0.740 >21 0.750 0.800 >22 0.770 0.760 >23 0.820 0.780 >24 0.760 0.740 >25 0.810 0.800 >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).

Re: [R] SORTING Arrays by index value
acc.gp.bl.wtmn[sort.list(row.names(acc.gp.bl.wtmn)), ] I am not clear how you missed order/sort.list, which have examples like this. It's referenced off ?sort. Indeed, sort() can be used too.

I want ascending order (1:25) of the index values. I think the `first column' is the row names. -- Brian D.
