Dear R users,   I am new user for elastic net. I am trying to use elasticnet library. I have marker data with 359 markers and 168 samples, and response is metabolites. I am trying to do regression between a metabolite and markers.  But i am getting the following error:   > en<-enet(marker,as.numeric(vio),lambda=0.5,normalize=FALSE,intercept=TRUE) Error in one %*% x : requires numeric

Dear R users, I have problem with extracting coefficients from a object. Here, X (predictor)and Y (response) are two matrix , I am regressing X ( dimensions 10 x 20) on each of columns of Y[,1] (10 x 1) and want to store the coefficient values. I have performed a Elastic Net regression and I want to store the coeffcients in each iteration. I got an error message . I do not

Hello, I am attempting to use elasticnet to classify a number of documents. The features are words. The data is coded into a matrix with each document as a row and each word as a column. The data is binary, with {0,1} indicating the presence of a word. I want to use the cross validation function of elasticnet (cv.enet). However, when the code selects a random subset of the data for a given

Dear all, I am using modified LARS algorithm (ref: The Adaptive Lasso and Its Oracle Properties, Zou 2006) for adaptive lasso penalized linear regression. 1. w(j) <- |beta_ols(j)|^(-gamma) gamma>0 and j = 1,...,p 2. define x_new(j) <- x(j)*w(j) 3. apply LARS to solve modified lasso problem out.adalasso <- lars(X_new,y,type="lasso") or enet(X_new,

New versions of the caret (3.08) and caretLSF (1.12) packages have been released. caret (short for "Classification And REgression Training") aims to simplify the model building process. The package has functions for data splitting, pre-processing and model tuning, as well as other miscellaneous functions. In the new versions: - The elasticnet and the lasso (from the enet package)

Dear R users, I am using "enet" package in R for applying "elastic net" method. In elastic net, two penalities are applied one is lambda1 for LASSO and lambda2 for ridge ( zou, 2005) penalty. But while running the analysis, I realised tht, I optimised only one lambda. ( even when I looked at the example in R, they used only one penality) So, I am

Can anybody help me to run the Elasticnet package of R to build some model, i am a freshman to R language , when i use the Elasticnet package to my data, it always reture a error, but i can't settle that problem. I consider if there is any constrant of the data to that package? Can anyone help me to run the elasticnet and check my data as you convenient? I put the data in attachment. Thank

Dear All, Thanks to an answer which I received from a previous post, I'm now able to create a series of environments using the following: nmes <- c("en1", "en2", "en3") for(i in nmes) assign(i, new.env(parent = .GlobalEnv)) My next question is how, using "load", can I automatically place data into each of these newly created environments. The

hello, i hav a prob in R lang. i want to do correlation of data frame 22810(gene) rows and 1436 colums(experiment) when i covert this file in csv or xls format it reads only 1024 cloumns. n when i do correlation of data mean 22810 *22810 matrix made in terminal then i export in csv or xls by write.table it will give me only 1024 columns rather than 22810 columns.wat i do plzzz help me...

Hi, I am having problems passing arguments to method="gbm" using the train() function. I would like to train gbm using the laplace distribution or the quantile distribution. here is the code I used and the error: gbm.test <- train(x.enet, y.matrix[,7], method="gbm", distribution=list(name="quantile",alpha=0.5), verbose=FALSE,

Have tried to install R.app several times (6, in fact: versions 2.12, 13 & 14, both 32 and 64 bit versions), using packages freshly downloaded from the official project page, and failed every time, given exception reports such as the following (appended below, the 2 reports arising out of my 1st & 6th attempts). Machine & software version specifics are all contained therein. What

So I won one of these on ebay, in the auction it says it has the RJ45 ports on it but it doesn't :( If I were to get an analog adapter would I be able to use the video portion of this or am I SOL? The auction requires me to pay for shipping back, so I end up losing money unless I sell it on my own. Or has anyone hacked these to work on enet?

Hello, I have installed and configured Samba 3.6.0 joining a Windows 2003 server domain. wbinfo -u works fine but when I try to access a share I get the following error : Failed to find authenticated user via getpwnam(), denying access Aix client is connecting the DC over a VPN.

I have a backup server now restoring 6TB of data to a client machine. This has been going on for four days now, and no sign of getting close to completion. The connexion is Gb enet end-to-end, and is running at only 40Mb/s. It has far more capacity than that. The only limiting factor I can see is on the backup server one core of the CPU is running 100% rsync. Clearly rsync is not

Hi Everybody! I must start with a declaration that I am a sparse user of R. I am creating a credit scorecard using a dataset which has a variable depicting actual credit history (good/bad) and 41 other variables of yes/no type. The procedure I am asked to follow is to use a penalized logistic procedure for variable selection. I have located the package "glmnet" which gives the complete
