similar to: Mutiplying a data frame to a list

Hello R community, I have been using R's inbuilt maximum likelihood functions, for the different methods (NR, BFGS, etc). I have figured out how to use all of them except the maxBHHH function. This one is different from the others as it requires an observation level gradient. I am using the following syntax: maxBHHH(logLik,grad=nuGradient,finalHessian="BHHH",start=prm,iterlim=2)

Hello R community, I have two questions about using R. The first is about dividing each element of a list with another similar sized list. So, if the first list has two elements and so does the second, then the result should also be a list with two elements. For example, the inputs are: list(matrix(1:6,ncol=2),matrix(1:6,ncol=2))->l1 l2<-list(1:3,2) I want to get a list, l3 with the

Hi, I have been using R for close to two years now and have grown quite comfortable with the language. I am presently trying to implement an optimization routine in R (Newton Rhapson). I have some R functions that calculate the gradient and hessian (pre requisite matrices) fairly efficiently. Now, I have to call this function iteratively until some convergance criterion is reached. I think the

Hello R community, I have two questions: The first might be one of the silliest ever posted here and I apologize if I've missed some thing very obvious. It relates to using this digest. When I subscribed to the forum, I had chosen the "digest" option that bundles all mails every day into a single digest. Now, I posted a question a while ago on the logistic regression function and

Hello R community, I have a question about the logistic regression function. Specifically, when the predictor variable has not just 0's and 1's, but also fractional values (between zero and one). I get a warning when I use the "glm(formula = ... , family = binomial(link = "logit"))" which says: "In eval(expr, envir, enclos) : non-integer #successes in a binomial

Hello: Forgive me, this is surely a simple question but I can't figure it out, having consulted the help archives and "Data Manipulation With R" (Spector). I have a list of 11 data frames with one common variable in each (prov). I'd like to use lapply to go through and recode one particular level of that common variable. I can get the recode to work, but it only returns the

Hi there, I have a list of dataframes (generated by reading multiple files) and all dataframes are comparable in dimension and column names. They also have a common column, which, I'd like to use for merging. To give a simple example of what I have: df1 <- data.frame(c(LETTERS[1:5]), c(2,6,3,1,9)) names(df1) <- c("pos", "data") df3 <- df2 <- df1 df2$data

Hi, I am doing poc for using libvirt api for implementation of esx in python. I tried researching through module but did not find a way how it works for esx. Any help on how to proceed specifically for esx would be of great help. Please let me know as soon as possible, lagging on deliverables. Thanks for help!! Regards Rohit Singh

Hi, This is a newbie question. I have been using glm to perform some logistic regression. However, if I take the fitted parameters (as part of the glm object) and pass them on the glm.predict function, for some test cases I am getting predicted values that are a little over 1. This is a bit puzzling for me, because my understanding was that these numbers are probabilities and so should be
