[R] Does roxygen work with S4 classes

Hi, I'm trying to run roxygen to generate Rdoc for code that define S4 classes. Apparently the files generated/updated by function 'roxygenize' don't follow the naming convention of package.skeleton myClass-class.Rd and myGeneric-methods.Rd. I've got duplicate files for each class and method,

[R] str(data.frame) after subsetting reflects original structure, not subsetted structure?

I find that after subsetting (you may prefer "conditional selection") a data frame and assigning it to a new object, the str(new object) reflects the original data frame, not the new one: A <- rnorm(20) B <- factor(rep(c("t", "g"), 10)) C <- factor(rep(c("h", "l"), 10)) D <- data.frame(A, B, C) s

Hi, can anyone tell me what a "roclet" is exactly? Is this terminology specific to R, or is it used in other languages aswell? -- aleblanc __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting

This should be very simple but I am wrestling with updating a data frame from within a function. Here is a simple example: ### SET UP DATA FRAME > tFrame <- data.frame(T=c(1:5)) > > tFrame T 1 1 2 2 3 3 4 4 5 5 > # Simple function that updates with 1000 > tUpdate<- function (x){ + tFrame$

Thank you for your reply. Yes I am reading that document and ofcourse simultaniously trying to apply in my current problem as well. Yes still I am learning. Here I have my code : library(ggplot2) library(plyr) dat = rnorm(1000); variable = rep(c("Variable:1", "Variable:2"), each=500); coll = rep

Does R has package for providing work for binary digit: arithmetic operation, convert to/from decimal digit, etc? I not found it, but think that CRAN contain it. [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://
