similar to: Potential bug with data.frame replacement

This may be related to the size of the deparsed call in the error message that Brodie and Luke were discussing recently on R-devel (" Mitigating Stalls Caused by Call Deparse on Error"). I don't get a crash, but the error message itself doesn't show up after the deparsed call. > X <- sample(letters, 3000, TRUE) > D <- data.frame(X, 1:3000, X, X, X, X, X) >

Luke, thanks for considering the issue.? I would like to try to separate the problem into two parts, as I _think_ your comments address primarily part 2 below: 1. How can we avoid significant and possibly crippling ?? stalls on error with these non-standard calls. 2. What is the best way to view these non-standard calls. I agree that issue 2. requires further thought and discussion under a

When large calls cause errors R may stall for extended periods.? This is particularly likely to happen with `do.call`, as in this example with a 24 second stall: ??? x <- runif(1e7) ??? system.time(do.call(paste0, list(abs, x)))? # intentional error ??? ## Error in (function (..., collapse = NULL)? : ??? ##?? cannot coerce type 'builtin' to vector of type 'character' ??? ##

We also have a few other suggestions and wishes about backtrace storage and display on the one hand, and display of constructed calls on the other hand. Perhaps it would be better to open a different wishlist item for traceback() to keep the discussions focused? FWIW I think deparsing backtraces lazily is a great idea. Displaying 1 line per call by default in interactive sessions, while being

Dear list member, I think that I have detected a strange behavior of the save() command: > year <- "2000" > assign(paste0("Var_", year), list(A=10, B=20)) > get(paste0("Var_", year)) $A [1] 10 $B [1] 20 # At this point all is ok, I have created a list of name Var_2000 > save(paste0("Var_", year), file=paste0("Var_", year,

Hi all, I'm not very used to CentOS and Linux generally speaking, though I read a lot and 'man' quickly became a very good friend of mine, right after Google, so sorry if that's a ridiculous one! (at least it'll give you a good laugh!) I updated the kernel to 2.6.9-42.0.2 recently and that raised a question... Simple... Yet silly...! What exactly is the difference between

Hi, I am having problem to display text that goes start inside the plot but should go over the margins of the plot. You can have an example of what I mean by looking at the graphs on this page:

Hi ! I am new to R, and using the MAC version onto Mac OS 9.1. My question concerns the problem I encounter when I try to read some data I have using the read.table function. I always get an error of type : Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 1 did not have 9 elements Here is my code: varnames <- c("names", "symbol",

I have the following (simplified) vectors: index <- c("shoe" "shirt" "fruit") cost <- c(100, 50, 2) data <- c("shirt", "shoe", "vegetable") I want my outcome to be: (50, 100, 0) (shirt => 50, shoe => 100, vegetable => not found, so 0) I have written the following function: for (i in custom_list) { + this_cost

Hi, I've been playing with CentOS quite a bit lately (and I must say it's growing on me!! :) and I was now able to convince my boss that we could get a box and gradually start migrating our hosting from win2k3 to centos. So anyway, I've got a new box at the colo ready up and running - P4 3Ghz w/HT 2Ghz RAM 2x70Gb HDD, running Centos4.4 fully up-to-date. Now my two questions are;

Hi Hugo, I've been able to replicate your bug, including for other distributions (runif, rexp, rgamma, etc) which shouldn't be surprising since they're probably all drawing from the same pseudo-random number generator. ?Interestingly, it does not seem to depend on the choice of seed, I am not sure why that is the case. I'll point out first of all that the R-devel mailing list is

Hi, I created a function for obtaining the normal cumulative distribution (I know all this already exists in R, I just wanted to verify my understanding of it). below is the code I came up with. cdf<-function(x) { erf<-function(x) { # approximation to the error function (erf) of the # normal cumulative distribution function # from Winitzki

Ni idea de eso; te lo agradezco. Seguramente lo voy a terminar usando bastante. Pregunto: ahí debería hacer todas las operaciones propias del sistema? No me encuentra el script, y se me hace raro. Capaz que pasa al sistema desde la carpeta en la que está el script de R, no desde el wd de R. Ahora me toca salir y después intentar probar y que funcione.
