Hi,
I am trying to figure out a "short" way to access two values output
from
the sort function.
x <- c(3,4,3,6,78,3,1,2)
sort(x, index.return=T)
$x
[1] 1 2 3 3 3 4 6 78
$ix
[1] 7 8 1 3 6 2 4 5
It would be great to do something like this (doesn't work.):
> yoursort <- function(x) {sx <- sort(x, index.return=T); return( c(sx
$x, sx$ix) )}
> yoursort(x)
[1] 1 2 3 3 3 4 6 78 7 8 1 3 6 2 4 5
c(y, indexes) <- sort(x, index.return=T)
But that doesn't work.
I CAN grab the output of sort in a variable and then access it twice
to
get the values, but that seems wasteful.
Any ideas?
