If so, is there any tutorial (not manual) or worked out example online for this R package that one can go through to figure out how one can use this package with lasso regression? I appreciate any help I can get in this direction.

Hello friends, I am trying to test NAS I/O performance over a network and trying to see the numbers for write and read speed. I have successfully configured and ran a lot of tests. However the numbers have not increased, I have reached a bottleneck. I tried playing around with the smb.conf file including all possible variations like, socket options = TCP_NODELAY SO_RCVBUF=(tried values like

...ction("pthread_create"), since the function might not be there in IR and then insert function calls to these functions. So, crux is how do i call pthread function calls into LLVM IR for a sequential program. Pardon me for such a basic doubt as I am a novice in llvm yet.

Hi useR's, I am resending this request since I got no response for my last post and I am new to the list so pardon me if I am violating the protocol. I am trying to use the "Kernlab" package for training and prediction using SVM's. I am getting the following error when I am trying to use the predict function: > predictSvm = predict(modelforSVM, testSeq); Error in

Hi All, This is more of a general statistics question that I am not so sure about so I need some thoughts from you experts out there. I have Chip-Seq read count data for 2 different treatments (T1 and T2) and my final aim is to calculate differential expression between them. I also have Chip-Seq read count data from a "control / wild type (C)" experiment. I have 3 replicates (2

I am using R with windows, 32 bit, version 2.9.0 Any help is much appreciated.

...3) It will take me a little time to understand the Xapian?s code and optimisation techniques in depth, so may I do research in depth in the time between 25th of March and 22nd of April and submit my proposal in a brief manner? Thanking you in advance Sanat Kumar Jain B.E. Computer Engineering Thapar University, Patiala India(GMT +5hr 30min) P.S. Sorry for sending my query so late, I had classes and to be honest, a little hesitation being a beginner which I just overcame. And I am sure that I will make a valuable contribution to the project this summer.

Hi, I apologize for posting this here, I am also trying to post this on machine learning emailing lists. I have a set (18K) of sequences (22 nt long) and I have their counts at 4 different stages. The difference in counts from one stage to the next represents how well the sequence performed in the transition. The total counts remain about the same in each stage. So if a 1 sequence loses some

Hi, I am writing to seek some guidance regarding using Lasso regression with the R package LARS. I have introductory statistics background but I am trying to learn more. Right now I am trying to duplicate the results in a paper for shRNA prediction "An accurate and interpretable model for siRNA efficacy prediction, Jean-Philippe Vert et. al, Bioinformatics" for a Bioinformatics project
