...he following works: x = 1 base::is.na(x) = TRUE However, the following fails: x = 1 b = baseenv() b$is.na(x) = TRUE The error message is "invalid function in complex assignment". Grepping the R code for this error message reveals that this behaviour seems to be hard-coded in function `applydefine` in src/main/eval.c: the function explicitly checks for `::` and :::` and permits those assignments, but has no equivalent treatment for `$`. Am I overlooking something to make this work? And if not ? unless there?s a concrete reason against it, could it be considered to add support for this synta...

Dear R-developers I came across the following issue, which I find strange: setClass("A", representation(a = "numeric")) B <- list() myA <- new("A", a = 1) B$otherA <- myA B$otherA at a <- 2 myA at a Assigning a new value to slot 'a' in the _copy_ of myA stored in B$otherA changes the original value of myA -- this was surprising to me, and I

For reasons which I'll spare you, I'm writing a program to analyse R source code. This has led me to probe some of the darker corners of R syntax to find out what is supposed to happen. Now, from reading the R documentation (and the New S book &c) I know perfectly well that f(a, b, etc) <- x is supposed to turn into a <- "f<-"(a, b, etc, value=x) Except,

If anyone has a few extra CPU cycles to spare, I'd appreciate it if you could verify a problem that I have encountered. Run the code below and tell me if it crashes your R before completion. library(lme4) data(bdf) dump<-sapply( 1:50000, function(i) { fm <- lme(langPOST ~ IQ.ver.cen + avg.IQ.ver.cen, data = bdf, random = ~ IQ.ver.cen | schoolNR); cat("
