selecting unique columns of a matrix/data frame
Hi all,
I have a very high dimensional data and apparently there are several
columns that contain similar information (some columns are equal). I
want to form a matrix/data frame consisting of unique columns. Does
anyone have an efficient way of getting out these columns. A small
section of the data frame is given below.
Thanks for helping.

AHRQ - Creation of Comorbidity Variables
If there are any other users who use AHRQ's SAS code comoanaly2010 and
comformat2010 to create comorbidity variables, I thought you might be
interested in the following PRELIM code we wrote to mimic its functionality
in R. It seems to yield similar results, but may contain errors. Please feel

Recently, I''ve been reading through the ZIL/slog discussion and
have the impression that a lot of folks here are (like me)
interested in getting a viable solution for a cheap, fast and
reliable ZIL device.
I think I can provide such a solution for about $200, but it
involves a lot of development work.
The basic idea: the main problem when using a HDD as a ZIL device
are the cache flushes

[PATCH v4 0/6] btrfs: generic readeahead interface
This series introduces a generic readahead interface for btrfs trees.
The intention is to use it to speed up scrub in a first run, but balance
is another hot candidate. In general, every tree walk could be accompanied
by a readahead. Deletion of large files comes to mind, where the fetching
of the csums takes most of the time.
Also the initial build-ups of free-space-caches and
