Dear my R friends, I want to get a number from a list using paste function. In my example, lambda.rule <- "lambda.1se" cvtest is a list (result from cv.glmnet) and cvtest$lambda.1se [1] 1.308973 I want to call the value using paste function. I used get function but there was an error. test <- get(paste("cvtest$",lambda.rule, sep="")) Error in

Dear All, I have data which contains 14 variables. And I have to regress one of variables on each variable (simple 13 linear regressions) I try to make a loop and store only R-squared colnames(boston) [1] "CRIM" "ZN" "INDUS" "CHAS" "NOX" "RM" "AGE" [8] "DIS" "RAD"

Dear All, I made a function which gives 3 plots in one window(I used par(mfrow=c(1,3)) in the function). Using that function 3 times, I want to produce 9 plots in one window. I tried par(mfrow=c(3,1)) or par(mfrow=c(3,3)) but it didn't work. For example, pf <- function(p) { par(mfrow=c(1,3)) plot(c(p:(p+10)),c(1:11)) plot(c(p:(p+10)),c(2:12)) plot(c(p:(p+10)),c(3:13)) } p <-

Hi. I am trying to generate a correlated binary data set. I've tried to use mvtBinaryEP, binarySimCLF, and bindata packages but none of them works in R version 2.15.1. Do you know any package to generate correlated binary covariates and work in R version 2.15.1, or how to generate it? Thanks, [[alternative HTML version deleted]]

Dear R users, Hi. I am using prediction function in ROCR package. y consists of two classes 0 and 1. However, since I am using cross-validation, a sampled small number of y may consist of only one class >y [1] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 In this case, prediction function gives an error: Error in prediction(predic, y) : Number of classes is not equal to 2. ROCR currently supports

Dear All, This is hard to describe so I made a simple example. set.seed(1001) total <- 0 data <- vector("list", 30) for(i in 1:30) { data[[i]] <- runif(50) } Let's call a data set runif(50). While the for loop is running, 100 data sets are generated. I want to restore 23th data set (the data set generated in 23th for loop) without the loop. I've tried set.seed(1023)

Dear listers, I am trying to install RcppBDT_0.2.1 on my Windows machine using the function install.packages("./RcppBDT_0.2.1.tar.gz", repos=NULL, type="source"). Since this package is not like most of other packages in that it requires Rcpp and boost, I have installed Rcpp and boost first, and executed the install.packages function. Then, I got the following error message:
