xYplot problem
Dear R community,
Since upgrading to R v.2.6.1 and re-installing package Hmisc (binary
for Mac OS X v.3.4-3), I have been getting a error when trying to
make xYplots:

Aggregate with non-scalar function
R-Helpers,
I'm sorry to have to ask this -- I've not used R very much in the last
8 or 10 months, and I've gotten rusty.
I have the following (ff2 is a subset of a much, much larger dataset):

convert into numeric variable
Hi,
I have an accounting data with "%" at the end and "()" for negative.
E.g. if I read in with read.table, then R reads in as a factor:
[11625] 4.61% ( 4.11%) 29.85% ( 1.27%) 16.04% 21.31% 14.09%
39.71%
[11633] 3.03% 17.39% 80.13%
6648 Levels: ( 0.00%) ( 0.03%) ( 0.04%) ( 0.05%) ( 0.06%) ( 0.07%) ...
99.70%

how to print table with more columns per row?
When printing a table it is broken at some point (depending how long are
the associated names)
>>> see example below.
Is there a way to control number of columns being printed for a given
chunk of the table?
Best regards,
Ryszard

Drawing thread not getting enough time from scheduler?
Need some assistance with animation again... When I run the drawing
code in a separate thread, it''s slow as heck. I think it may be
because the drawing thread isn''t getting enough time from the thread
scheduler.
I was able to reproduce the problem in my little sample program simply
by increasing the number of lines it draws per update. I''m lucky to
get one frame

Vorbis/Lame
Hi,
I think that it would be a good thing to know more about those 2 projects
(and also the future patent free format).
I think that many people as me know about Lame, but not about Vorbis, and
vice-versa.
It would be fine that someone (perhaps the maintainer) of every project
would introduce to both group of people those projects. 2 things would be
interesting (to my mind):

Slow performance of gluster volume
OK my understanding is that with preallocated disks the performance with
and without shard will be the same.
In any case, please attach the volume profile[1], so we can see what else
is slowing things down.

Scaling Asterisk: Dual-Core CPUs not yielding gains at high call volumes
List users,
Using Asterisk in an inbound call center environment has led us to
pushing the limits of vertical scaling. In order to treat each caller
fairly and to utilize our agents as efficiently as possible, it is
desirable to configure each client as a single queue. As far as I know,
Asterisk's queues cannot be distributed across servers, so the size of
the largest queue we service

Slow performance of gluster volume
Hi Krutika,
I already have a preallocated disk on VM.
Now I am checking performance with dd on the hypervisors which have the
gluster volume configured.
I tried also several values of shard-block-size and I keep getting the same
low values on write performance.
Enabling client-io-threads also did not have any affect.
The version of gluster I am using is glusterfs 3.8.12 built on May 11 2017

Unreasonably poor performance of replicated volumes

Unreasonably poor performance of replicated volumes
Guess you went through user lists and tried something like this already
http://lists.gluster.org/pipermail/gluster-users/2018-April/033811.html
I have a same exact setup and below is as far as it went after months of
trail and error.
We all have somewhat same setup and same issue with this - you can find
same post as yours on the daily basis.

Unreasonably poor performance of replicated volumes
Thanks a lot for your reply!
You guessed it right though - mailing lists, various blogs, documentation,
videos and even source code at this point. Changing some off the options
does make performance slightly better, but nothing particularly
groundbreaking.
So, if I understand you correctly, no one has yet managed to get acceptable
performance (relative to underlying hardware capabilities) with

Summary statistics for matrix columns
Hi,
is there a way I can calculate a summary statistics for a columns matrix
let say we have this matrix
x <- matrix(sample(1:8000),nrow=100)
colnames(x)<- paste("Col",1:ncol(x),sep="")
if I used summary
summary(x)
i get the output for each column but I need the output to be in matrix with
rownames and all the columns beside it
this how I want it
