Dear R Users,I have a data set with several variables. One of these variables is the number of farms per county and I'd like to split this variable into two domains: (a) counties with fewer than 600 farms and (b) counties with 600 or more farms I've tried solving this problem for hours, but I'm

[R] Non-Linear Optimization - Query

Dear All, I couple of weeks ago, I’ve asked for a package recommendation for nonlinear optimization. In my problem I have a fairly complicated non-linear objective function subject to one non-linear equality constrain. I’ve been suggested to use the *Rdonlp2* package, but I did not get any

[R] - help - predicting with glmnet/lars for dataframes with different nrow then the train set

Hello I'm having trouble using lars and glmnet functions to predict on a new data set with different nrow then the original : for instance: = log.1 = glm(temp.data$TL~(.),temp.data,family = binomial,x=TRUE,y=TRUE) nrow(test.data) != nrow(temp.data # == TRUE Val.frame =

[R] Calculate across columns

I'd like to perform some calculations across a series of columns. Is there an easy way to do so? For example, I'd like to calculate the maximum value from columns 6-42. Although I can use, say: pmax(data[,6],data[,7],data[,8], etc.), I'd prefer to be able to do something like pmax(data[,6:42]).

[R] the effect of blocking on the size of confidence intervals - analysis using lme and lmer

This is a follow-up mail of the effect of blocking on the size of confidence intervals - analysis using aov. In both mails I pursue the idea of using blocking factors in order to reduce the width of confidence intervals. My dataset comprises, a quantitative response variable, namely: response,

Hi, I am a method developer in drug discovery. I have developed a similarity searching method for small (drug-like) molecules. I want to compare the performance of my method to the performance of other methods. Similarity searching methods are commonly assessed by their ability to (re)discover a

Dear all, I am using the bigglm package to fit a few GLM's to a large dataset (3 million rows, 6 columns). While trying to fit a Poisson GLM I noticed that the coefficient estimates were very different from what I obtained when estimating the model on a smaller dataset using glm(), I wrote a
