To make sure everyone’s on the same page, Walking Sparrow’s approach is
completely standard for R. The way that R treats certain DataFrames as an
additional scope in which to search for variable bindings is something R users
have been taught to expect, even though it is an extremely un-Julian
I think you want sortperm.

Is there an easier method to obtain the sorting index given a column of data?
In Matlab you can add a second output and it'll give you an index which you
can apply to other related arrays.
Yes, assuming we can get the builds working smoothly, it would be really great
to offer stable and unstable binaries right on the main downloads page.

This is definitely on purpose.
Quick summary:
* DataMatrix is a mathematical object
* DataFrame is a database
We're going to encourage use of colwise for some of these use cases. But for
many of them we're going to encourage the use of DataMatrix instead.

Hi all,
Over the coming weekend, I am going to move Clustering.jl to JuliaStats. I
hope the move will go smoothly, but am always wary about changing repo URL’s.

FYI, this claim about the safety of symbols is actually not true. You can
reassign the bindings of sym just as easily as you can reassign the bindings of
a variable bound to a.

In the interest of getting some eyes on the DBI library without breaking Jacob
Quinn’s substantially more stable SQLite.jl package, I’ve created a new
