Rahul Agarwal Analyst Equities Quantitative Research UBS_ISC, Hyderabad On Net: 19 533 6363 hi let me explain you the problem we have a database which is in this format Stocks 30-Jan-08 28-Feb-08 31-Mar-08 30-Apr-08 a 1.00 3.00 7.00 3.00 b 2.00 4.00 4.00 7.00 c 3.00 8.00 655.00 3.00 d 4.00 23.00 4.00 5.00 e 5.00 78.00 6.00 5.00 and we have a query

Dear all, I would like to aggregate a data frame (consisting of 2 columns - one for the bins, say factors, and one for the values) along bins and quantiles within the bins. I have tried aggregate(data.frame$values, list(bin = data.frame $bin,Quantile=cut2(data.frame$bin,g=10)),sum) but then the quantiles apply to the population as a whole and not the individual bins. Upon this

I discovered recently that the phrase "Oja median" produces no hits in Jonathan Baron's very valuable R search engine. I found this surprising since I've long regarded this idea as one of the more interesting notions in the multivariate robustness literature. To begin to remedy this oversight I wrote a bivariate version and then decided that writing a general p-variate version

1. I have a list of lm (linear model) objects. Is it possible to select, through subscripts, a particular element (say, the intercept) from all the models? I've tried something like this: List[[1:length(list)]][1] All members of the list are similar. My goal is to have a list of the intercepts and lists of other estimated parameters. Is it better to convert to a matrix? How to do this? 2.

Hello, I have a pre-built xen image from jailtime.org (centos.5-2.64.img). However, I cannot get it to boot.

Hello All! I have a question regarding the package RDCOMClient. I want to start an Excel file with R and it works flawlessly except the fact, that Add-Ins are not loaded. Can someone please explain me how to load one? Does it work with ex$AddIns$Invoke? Greetings, David [[alternative HTML version deleted]]

---Adding llvm-dev list to CC--- Hi Alberto, Thanks for your prompt reply. Actually, I need this information(about total allocation size and object structure) on runtime, so that is why I was planning to encode this info and store it in the memory itself.

Hi guys, I have configured Samba share drives on my CentOS 7 VSI, and using OpenVPN client for the users to access these shares from Windows or MAC. While I am trying to upload/download heavy files (>500MB) it is very slow in speed. Any suggestions? Thanks, Shobhit Agarwal -- Regards, Shobhit Agarwal +61-406528285

Dear All, Sorry to trouble again..... After go through www.lartc.org I have implemented the HTB instead of CBQ for the same scenario. Now following files are under /etc/sysconfig/htb directory. eth0 DEFAULT=30 R2Q=10 eth0-2.root RATE=256kbps BURST=25k eth0-2:10.comp1 RATE=120kbps BURST=12k PRIO=0 LEAF=sfq RULE=192.168.200.0/24 eth0-2:20.comp2

Hello all, In my project, I need to allocate an extra 4 Bytes in every Alloca instruction. These additional bytes will be used to store the 'allocation info'(like size and structure of the allocated object etc). Instead of adding 4 bytes to the Alloca 'size' operand at every Alloca Instruction, I was thinking to make this change at the level where Alloca gets converted to machine

Hi. I am a little unclear about the ARM JIT support status. Is it working as of LLVM 3.1? If not, is it on the roadmap for LLVM 3.2? I am not currently interested in NEON support so if thats unimplemented, thats fine. thanks, Rahul

Hi, How can I read multiple files(in a loop like manner) within a single code of R ? For example, I need to run the same code for different datasets (here list of companies) and since individual files are quite large, appending the files into one file is not a desirable option. Can this be done through a macro or sql kind of command? Thanks and Regards, Rahul S Menon Research Associate ISB,

Hi, I am trying to understand and change the network buffering that is being used by Remus, the HA solution present in Xen. From what i understood from reading the code, Remus calls the postsuspend method of the BufferedNIC after it suspends the domain that sends TC_PLUG_CHECKPOINT message and start the buffering and then calls the commit method of BufferedNIC after it gets the acknowledgement

I'd like to plot data that's in the form of a table such as this: 1 2 4 6 8 12 a 10 11 12 14 15 30 b 2 3 3 4 5 5 c 1 1 2 2 3 3 Where the row headers are the results for different series of tests, and the column headers are the x-values. I'd like to plot this as a set of lines, one each for "a", "b", and "c". I can rearrange the data as needed, but
