Sort matrix by column 1 ascending then by column 2 decending
I've got a matrix with 2 columns and n rows. I need to sort it first by the values in column 1 ascending. Then for values which are the same in column 1, sort by column 2 decending. For example: 2 .5 1 .3 1 .5 3 .2 Goes to: 1 .5 1 .3 2 .5 3 .2 This is easy to do in spreadsheet programs but I can't seem to work out how to do it in R and haven't been able to find a solution anywhere.
