similar to: read input from STDIN

Hello, all, I have a question regarding data input. For example: I have a file like this Group exp value 001 1 1 5 002 1 2 4 003 1 3 4 004 2 1 4 005 2 1 4 006 3 2 3 007 3 4 5 008 3 4 5 009 3 5 6 I read it using f<-read.table("infile") we have 3 groups here, group1 have 3 exps group 2 havs 2 exps group 3 has 4 exps After I read the file,

Hi, I work with SEXP C code and with xts and quantmod packages. I try to touch how xts internal works. So we have R session and: > ls() character(0) > getSymbols('AAPL') # quantmod package [1] "AAPL" > ls() [1] "AAPL" > str(AAPL) An ?xts? object from 2007-01-03 to 2010-09-09 containing: Data: num [1:929, 1:6] 86.3 84 85.8 86 86.5 ... - attr(*,

Hi all, I would like to flag each record in the data according to certain conditions as specified below. For example, If "Close_date" in *dat* is between ("Open" & "Close") or ("Open1" & "Close1") or ("Open2" & "Close2") in *oc, *flag the records as "Valid", otherwise "Invalid" I would like to

Hello, I am trying to communicate with R from a perl program. Because this code must be deployed on systems that are outside of my control I do not wish to pursue the RSperl.pm approach which requires that R be compiled to use shared libraries. I have a custom, light weight module I have used with other command line driven programs like Ferret and Grads. This module follows the standard perl

Yeah. We need to have more extra fields in the instruction. Fo example, during high-level synthesis, we must schedule an instruction to a certain control step (or cycle), and bind it to be execute on a certain functional unit, etc. Besides the in-memory exchange of the information, we also want on-disk exchange. That introduces the write-out/parse-in problem. Thanks ----- Original Message -----

Hello- Does anyone have a recommendation on how to call R from perl? I'm using the IPC::Open2 module, and running R with the --slave and --quiet options. The problem is that I can't predict how many lines of output I should try to read for each command-- if any! The ultimate goal is to use perl to provide a form-driven web interface, but have R do the underlying calculations. Thanks

Hi, all, I'd like to find one or more changepoints in a dataset eg for data like 0.9 1 0.8 0.8 0.85 0.3 0.9 0.9 0.9 1.1 0.3 is unlikely a changepoint but for data like 0.9 1 0.8 0.8 0.85 0.3 0.2 0.2 0.1 0.2 0.3 0.3 is a change point I am wondering is there any function can do changepoint analysis?

I'm CC'ing the llvm-dev list because other people are more knowledgeable about the bytecode format/encoding than I am. Please follow-up the replies to the list.

Hi all, The topic of creating a unified API for open3 for Windows came up at RubyConf 2004 this year. Park, I was wondering if you would mind if we modified win32_popen so that the API matches the open3 library that ships with Ruby. This also means deciding whether or not to leave in the open2, open4, and posix stuff. I guess it doesn''t hurt to leave this in, although Open3.open4

Vikram, I also agree with you. I understand that target-independent representation is very valuable and important for software compilation. However, when we are doing high-level synthesis (also called behavioral/architectural synthesis), the targeting architecture is also changing. That is, we need to do architecture exploration and the IR transfromation simultaneously. For example,

Yiping, Could you describe in a little more detail what your goals are? I agree with Reid and Misha that modifying the instruction definition is usually not advisable but to suggest alternatives, we would need to know more. Also, for some projects it could make sense to change the instruction set. --Vikram http://www.cs.uiuc.edu/~vadve http://llvm.cs.uiuc.edu/ On Oct 20, 2004, at 2:41 PM,

Hi, Yiping! I am not sure of the answer to your question, but I am forwarding it to the LLVMdev list where I am sure someone will be able to answer you. Please send development questions directly to LLVMdev and you will get a response quicker, as it is read by many LLVM developers. ----- Forwarded message from Yiping Fan <fanyp at cs.ucla.edu> ----- Date: Mon, 31 Oct 2005 17:20:24 -0800

In my previous mail the last line was supposed to be: "It turns out I probably won''t use fork unless support FOR STREAMS is added to it." aslak

domUloader potentially makes my life a lot easier, but from experiments and looking at the code, it doesn''t seem like there is any way to pass kernel command line arguments with it. Am I just missing something? Thanks, John Byrne _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

First of all, GREAT WORK! I now have my very own Windoze domain thanks to Samba :) Now, getting Samba to work fully on OpenBSD was harder than I'd think it would be. To get smbd to compile somewhat cleanly, I had to hack ./source/include/config.h thusly: remove USE_SETREUID, add USE_SETEUID. Then, I hacked sec_ctx.c like the attached diff shows, to get rid of some assert_gid panic when

Hi R users, I request members of the R community to consider filling a short survey regarding the use of R. The survey can be found at http://goo.gl/jw1ig Please accept my apologies for posting here for a non-technical reason. The data collected will be suitably analyzed and I'll post a link to the results in the coming weeks. Thank you all for your interest and for sharing your R usage

Hi, all: I can't make my HP DL380 G2 servers to boot off local disk by using "default local" line in my PXE boot menu. For fully automated server setups, I have configured all my DL380 servers to always do PXE boot. By manipulating the default boot option in boot menu, I can control a server whether to install a new OS via kickstart or just boot off local disk. This scheme works

Some packages want to pass input to gcc via STDIN (iptables for example) This patch lets klcc accept '-' as a valid input filename, prevents it from setting -x in that case and changes the invocation of gcc from system() to open3() so that gcc's STDIN can be connected to klcc's STDIN.
