<div>Dear Gang -<br>
<x-tab> </x-tab>Two questions for you:<br>
<x-tab> </x-tab>1) I cannot figure out how to sort one
column in an array, and drag the rest of the values that occupy the
other columns along with the sorted values in the first column.
What I would like to end up with is an array that is the same size and
dimensions as the first array. When I try various configurations
of sort, I keep getting vectors instead of the array I started with,
and I have not found a way to make sort "bind" other values
to the sorted values.<br>
<x-tab> </x-tab>2) I used a PC version of R
over the summer, and was able to use rowSum, colSum and similar
functions. These (and other things) do not seem to be enabled on
the Mac OS9 version. Are they enabled on the OS10 version?
If not, how can I enable them? And how do I download the OS10
version? My computer does not recognize the .gz files on the
website http://cran.r-project.org/bin/macosx/atlas/.<br>
<x-tab> </x-tab>Many thanks,<br>
