similar to: Small changes to big objects (1)

Back to the scenario in my email of Jan. 3: We have objects with some large (or very large) components and some other components as well. We need to modify the smaller stuff but are not changing the big data. How can we avoid copying the big data? (A use case might be some modeling of large data where we want to save various versions, all including the same original data but differing in

Hi All, Newbie question for you all but i have been looking at the archieves and the help dtuff to get a rough idea of what i want to do I would like to merge two dataframes together based on a keyed variable in one dataframe linking to the other dataframe. Only some of the cases will match but i would like to keep the others as well. My dataframes have 67 and 28 cases respectively and i would

Hi All, I've finally gotten around to database access using R. I'm happily extracting rows from a MySQL database using RMySQL, but am having problems appending rows to an existing table. What I *want* to do is to append rows to the table, allowing the database to automatically generate primary key values. I've only managed to add rows by using dbWriteTable( con,

Hi  I have a dataframe similar to: >Sample<-c(1,1,1,2,2,2,3,3,3) >Time<-c(1,2,3,1,2,3,1,2,3) >Mass<-c(3,3.1,3.4,4,4.3,4.4,3,3.2,3.5) >mydata<-as.data.frame(cbind(Sample,Time,Mass))   Sample Time Mass 1      1    1  3.0 2      1    2  3.1 3      1    3  3.4 4      2    1  4.0 5      2    2  4.3 6      2    3  4.4 7      3    1  3.0 8      3    2  3.2 9      3    3

Dear All... I need some information regarding OCFS performance in my Linux Box, herewith is my environment details : 1. We are using RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2. OCFS version : 2.4.9-e-enterprise-1.0.9-6 3. Oracle RDBMS : 9.2.0.4 RAC with 5 Nodes 4. Storage = EVA 6000 with 8 TB SIZE 5. We have 1 DiskGroup and 51 LUNs configured in EVA6000. My Question is : 1. It takes arround 15

Hi, currently I am running Solaris 8 and I am trying to install Samba so that I can run smbsh to access a Windows server. I do the following: ./configure --prefix=/usr/local/samba --with-smbwrapper make make install All the documentation I have seen says what I am doing is correct. Neither the configure nor any of the make commands fail. And once the installation is complete everything else

Hello llvm-dev, Following up on the "CodeGen Context" discussion that was started, attached is patch which implements a pretty minimal skeleton of a CGContext implementation. The goal is to allow the newly added subtarget attributes on functions to be made available to codegen so that codegen can actually switch subtargets within a Module. Comments and questions are invited herewith.

Hi, We have a scenario where inbound calls from an upstream provider (chan_sip) sent downstream (chan_iax2) negotiates only g729 yet RTP media contains g711. Both the upstream and downstream trunks are limited to only offering g729 whilst the initial invite from our upstream provider offers both g711 and g729. Asterisk presumably simply forwards the media from iax2 trunk encapsulation to sip

Hey all... I was writing a Function pass to print all the functions using runonFunction() method .but it is printing one global variable "x" at the same time which i just dont know how is getting there.how can i avoid "x" from printing?? . Here is the framgment of code of my pass namespace { // Hello - The first implementation, without getAnalysisUsage. struct Test2 :

Sir, I want to solve the equation Q(u)=mean, where Q(u) represents the quantile function. Here my Q(u)=(c*u^lamda1)/((1-u)^lamda2), which is the quantile function of Davies (Power-pareto) distribution. Hence I want to solve , *(c*u^lamda1)/((1-u)^lamda2)=28353.7....(Eq.1)* where lamda1=0.03399381, lamda2=0.1074444 and c=26104.50. When I used the package 'Davies' and solved Eq 1, I got the

Dear Sirs, ? At the outset I sincerely apologize for reproducing my query to you. I also thank all of you for the solution you had provided. It has worked on the actual data I am working with. ? However, there is this peculiar problem which I had realized only after I had obtained my results. ? e.g. in the example I had attached ? A?<-?c(2, 2, 1, 3, 7, 3, 3, 1,?14, 7, 31) B?<-

Dear R Gurus: How do I find the functions which are primitives, please? Thanks, Edna Bell

Hi OCFS Gurus... I have 2 questions for OCFS ver 1.0.10.1 1. What is the Maximum mount point suggested if we are using OCFS ? 2. Is there any method to tune the OCFS to booster the IO performance? Awaiting ur responses... Thanks in Advance... Rgds/Jeram

Hi all, Attached herewith is a simple vectorized function with loops performing a simple shuffle. I want all loops (inner and outer) to be unrolled by 2 and as such used -unroll-count=2 The inner loops(with k as the induction variable and having constant trip counts) unroll fully, but the outer loop with (j) fails to unroll. The llvm code is also attached with inner loops fully unrolled. To
