similar to: unlisting a list with names components (PR#645)

hi - i apologize if this is a duplicate. i think the lines below demonstrate a problem with unlist when the list contains components that are names. _anything_ can go in a list, right? this came up in the context of trying to unlist(list(attr(terms(formula), "variables")). perhaps unrelated but i thought i'd mention: unlist() complains about a call/formula object, but sapply()

Original incorrect subject line was Subject: [Rd] multi.line=FALSE does not work in scan() (PR#1210) It *does* work quite correctly: this was an erroneous file nd you got an error, just one you didn't understand.

Can we unlist defunct builders? For example, none of the bots running on the dunbar1 slave have been building for months. They just clutter up the waterfall view. Cameron

This example is caused by R's messing with formula environments. That's explained in ?formula, but should it not be explained in ?model.frame ? Simple test: data <- data.frame(y=rnorm(100), x=1:100) testit <- function(formula) { weights <- runif(100) glm(formula, weights=weights, data=data) } testit(y ~ x) weights is looked for in the environment of the formula, not of

Hello everyone, What is the most efficient & simpliest way to convert all components of a list to separate columns in a matrix? Is there an easy way to programmatically "pad" the length of the resulting shorter character vectors so that they can be easily combined into a data frame? I have the following code that stores the 2 compoents (of differing lengths) in the same character

Thank you for Prof.Ripley's suggestion.

Perhaps the following example will help demonstrate that matrix lists do exist and do work up to a point, despite strident assertions on R-help to the contrary: > m <- list(a1=1:3, a2=4:6, a3=pi, a4=c("a","b","c")) > dim(m) <- c(2,2) > m [,1] [,2] [1,] "Numeric,3" "Numeric,1" [2,] "Numeric,3"
