how to manually enter an double quote as data feed?
I'm doing a text mining project where I have to manually enter a double quote
as an element inside a vector.
I tried
char[10]='"'#where i enclosed the double quote in a pair of single quotes.
But the result is [1] "\"". Somehow a back slash is added automatically.
I also tried to enclose the double quote in a pair of double quotes. That
didn't work either.

how to find unique pairs of variables?
I have two variables, both numerical. I would like to find the unique
values of the pairs, in other words, unique coordinates if I were to
plot them.
I also need to know how many pairs there are, but I guess I can use
length() if I can somehow isolate the unique pairs first?
Thanks a lot!

difference between createPartition and createfold functions
Hello,
I'm trying to separate my dataset into 4 parts with the 4th one as the
test dataset, and the other three to fit a model.
I've been searching for the difference between these 2 functions in
Caret package, but the most I can get is this--
A series of test/training partitions are created using
createDataPartition while createResample creates one or more bootstrap
samples.

map at fips level using multiple variables
Hi, I just started playing with county FIPS feature in maps package
which allows geospatial visualization of variables on US county level.
Pretty cool.
I did some search but couldn't find answer to this question--how can I
map more than 2 variables on US map? For example, you can map by the
breakdown of income or family size. How do you further breakdown based
on the values of both

import csv file into R, strange problem
Hi, I used read.csv(file name, header=T, sep=",") to bring in a csv file I
saved in MS Excel. The strange thing is all the data ended up in one big
column. The number of rows match with the number of observations, but all
the variables got squeezed into one column. Also the first row where the
header is, the variables names have a dot between them, replacing the comma

ocfs seek-performance
hi list,
i have a little problem with 2-node RAC using OCFS. the application running on this cluster does
heavily index-based accesses. the data volumes are SAN volumes connected by fibrechannel.
the throughput does not exceed 10mb/s, average is 7-8 mb/s. i've used 'iostat -x' and got rkB/s=8000
while %util=100% (device was saturated) from kernel's POV.

Tar Compression issue
I have a file Server CentOS 5.10, its on the internet, so I compress all csv
into one file using (tar -czvf compressed_files.tar.gz *.csv) on this
server so that I can download them as one compressed file to save bandwidth,
Disk space on this server available is 50Gig, so when I copy the files onto
Redhat EL 5.9 and decompress them using (tar -zxvf *.gz) It decompresses
maybe 80% then get error:

bug in glm()? (PR#3223)
Full_Name: Bonnie
Version: 1.6.1
OS: Windows
Submission from: (NULL) (160.129.25.106)
glm() seems to converge, even when it shouldn't. I am trying to fit a model
where $converge=FALSE and I am fitting models that do not converge in SAS,
but they seem to converge in R ...
Thank you.

benchmarking large RAID arrays
I'm just wondering what folks are using to benchmark/tune large arrays
these days. I've always used bonnie with file sizes 2-3 times physical
RAM. Maybe there's a better way?

Physical disks + Software Raid + lvm in domU
Hi,
I''m trying to setup my box as described below:
- The Dom0 exports two disks as physical devices to the DomU
- DomU use the two devices to assemble a software raid device (/dev/md0)
- On the /dev/md0 I create a lvm volume group and lvm volumes on it.
Everything seems to work fine if the lvm volumes on the DomU are lightly
used. Under heavy load the DomU freeze up immediately.

SAMBA and Active Directory Intergration Problem
I have a CentOS6.3 SAMBA file server. All the users are on a Windows Server 2008 Active Directory Domain Controller and authentication is done using Winbind integration on SAMBA .
Everything works well except that if someone logs on to the Samba Server, they see all the shared folders there and also a folder with their own name %USER%. This Folder is not accessible, one cannot enter into this

Another printing problem...
I'm running samba 2.2.3a-6 under Debian (testing) and I
am having a heck of a time getting Windows 2000 to print
to my printer. I keep getting that "Access denied, unable
to connect" message. At one point I had it so you could
print test pages, but as soon as you tried to print from
an application, it would break. However, that doesn't
even work anymore. I've been reading

EXT3 with 2.2.20 - Is it stable enough for a production server th at is used 24X7?
Hello All,
I have a production server that is running 2.2.20. This server *has* to be
up 24X7 - what I'm wondering is:
1) Is ext3 on 2.2.20 rock stable? Or, would you recommend that I just stay
with ext2?
2) I have looked far and wide for a the ext3 patch for 2.2.20 - where can I
find it?
3) Were are the e2fsprogs that are appropriate to run with the 2.2.X kernel
series?
Thanks,

RAID benchmarks
We (a small college with about 3000 active accounts) are currently in
the process of moving from UW IMAP running on linux to dovecot running
on a cluster of 3 or 4 new faster Linux machines. (Initially using

As we are building and designing the system, I'm attempting to take (or
