similar to: stuck with repeated values

Hi, I am facing a problem in data manipulation. Suppose a data frame contains two columns. The first column consists of some repeated characters and the second consists of some numerical values. The problem is to extract and create a new data frame consisting of rows of each unique character of first column with minimum second column entry. For example if "d" is the data

Hi Can anybody please suggest me about the documentation of "factanal.fit.mle()" (Not factanal()------ searching factanal.fit.mle() in R always leads to factanal()). Is there any function for doing principal component factor analysis in R. Regards Souvik Bandyopadhyay JRF, Dept Of Statistics Calcutta University [[alternative HTML version deleted]]

Hi Is there any way to fit a bivaraite longitudinal mixed model using R. I have a data set with col names resp1 (Y_ij1), resp2 (Y_ij2), timepts (t_ij), unit(i) j=1,2,..,m and i=1,2,..n. I want to fit the following two models Model 1 Y_ij1, Y_ij2 | U_i = u_i ~ N(alpha + u_i + beta1*t_ij, Sigma) U_i ~ iid N(0, sigu^2) Sigma = bivariate AR structure alpha and beta are vectors of order 2.

Greetings, (I am reposting this email of mine, as I was informed that emails from the domain 'iith.ac.in' are sometimes being marked as spam) I am Aradhya Biswas, final year student of Computer Science and Engineering at Indian Institute of technology Hyderabad (IITH), and as mentioned in my previous email on the LLVM dev mailing list, I am interested to work towards the improvement of

Hello everyone I am Rakshit Singla, a third year undergrad at IIT Hyderabad, India. I finished a basic compilers course last semester and am currently doing a compiler optimizations course. I have been exploring LLVM for the past few months (wrote a front-end for the Classroom Object Oriented Language and have been studying pieces of code.) I would like to work with LLVM and contribute to the

Dear LLVM Community, I am D Tharun Kumar, masters student at Indian Institute of Technology Hyderabad, working in a team to improve current vectorizer in LLVM. As an initial study, we are studying various benchmarks to analyze and compare vectorizing capabilities of LLVM, GCC and ICC. We found that vectorization remarks given by LLVM are vague and brief, comparatively GCC and ICC are giving

The GVN algorithm used in LLVM currently (I'm rewriting it) is the basic hash based RPO algorithm. The new one i'm writing is based on http://dl.acm.org/citation.cfm?id=512536 (see https://github.com/dberlin/llvm-gvn-rewrite) LLVM has different algorithms for both scalar PRE and load PRE. They are basically variants of standard PRE algorithms transformed into SSA, but with some

Hello all, We are students from Indian Institute of Technology(IIT), Hyderabad, we would like to propose the addition of the following pragmas in LLVM that aide in (or possibly increase the scope of) vectorization in LLVM (in comparison with other compilers). 1. ivdep 2. Nontemporal 3. [no]vecremainder 4. [no]mask_readwrite 5. [un]aligned Could you please

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? Thank you in advance. Arnab Kumar Maity Researcher Indian

Dear All, Kindly tell me the steps to perform analysis of covariance (ANCOVA). Can I find anything in the help().

Hi Dangeti, Ramakrishna, Adam, and Gerolf, >Yes this is an area that needs further improvement. We have some immediate plans to make these more useful. See the recent llvm-dev threads [1], [2]. It takes a lot of dedicated effort to make vectorization report easier to understand by ordinary programmers (i.e., those who are not compiler writers). Having done that for ICC ourselves, we truly

Hi Folks, We are a group of LLVM compiler developers in Hyderabad area. Considering few previous mail about meetups in India, we are planning to organize LLVM meetups in India evry monthly or bimonthly in the best interest of other developers. Based on the concentration of developers Pune, Bangalore and Hyderabad are the location we have in mind. Interested folks please reply stating ur

Hi, I have a bivariate longitudinal dataset. As an example say, i have the data frame with column names var1 var2 Unit time trt (trt represents the treatment) Now suppose I want to fit a joint model of the form for the *i* th unit var1jk = alpha1 + beta1*timejk + gamma1* trtjk + delta1* timejk:trtjk + error1jk var2 = alpha2 + beta2*timejk + gamma2* trtjk + delta2* timejk:trtjk +

dear list, as a part my problem. I have to estimate some parameters using ML estimation. The form of the likelihood function is not straight forward and I had to use a for loop to define the function. I used "optim" to maximise the result but was not sure of the programme. To validate my results, I tried to write a function to obtain the MLE of a bivariate normal in the same manner. On

Hi, I am interested in applying to LLVM as part Google Summer of Code 2015. I have been going through LLVM code since about 4 months now, and while going though mailing list discussions I found particular interest in the point raised by Arch Robinson in January about the development of a floating point range check pass in LLVM. I have been in touch with Arch as well as Hal Finkel about this and

> There is a fundamental problem with the way that ivdep is defined by Intel's current documentation, at least for C/C++. As you note in your Google doc, it essentially says that the optimizer may ignore loop-carried dependencies except for those dependencies it can definitely prove are present. These are not semantics that any other compiler can actually replicate, and is not equivalent to

Hi all, I have n no. of extensions in my dialer. from 456 to 556 extensions. I was created 2 other extensions 667 and 668 I need to allow only STD calls to go from this extensions. These all extensions are same context . I need to define the STD dialplan for only this 2 extensions. how I can ?
