Hi, I'm looking for a way to generate a "full stop" that will not be caught by signal handlers, cf. .Internal(.dfltStop(msg, call)). RATIONALE: In the R.oo package I have throw() which (leaving out some details) basically does what stop() does but appends a stack trace string to the error message that shows up at the R prompt. Example: bar <- function() throw("A foo

Hello, If repeated calls are made to save() using the same pre-opened gzfile connection to a file, and then the connection is closed, the objects saved by the second and subsequent calls are not correctly restored by repeated calls to load() with a new gzfile connection to the same file. What follows are a session exposing the bugs, analysis (see ANALYSIS), patches (see PATCHES), and a session

Dear list, I'm getting some strange behavior with Reference Classes every once in a while and I can't really put my finger on the cause. It'd be great if someone using Reference Classes could check if he/she experiences similar problems: The thing is that when I alter the definition of a Reference Class in a running R session and source the respective file containing the class

I have a little problem about method dispatch and "unnessary" copying. Basically what I would like to do is: `[.myclass` <- function(x, i,j, extraopt=TRUE/FALSE, drop=TRUE) { ...do stuff depending on extraopt... value <- Nextmethod("[", x, i,j, drop=TRUE) ... do more stuff depending on extraopt... } I have two general problems: (1) NextMethod() really

'?removeClass' shows that 'removeClass' is from package 'package:methods'. Is there a command which can show me all the functions and the classed defined in a package such as 'package:methods'?

Hello! Recently I got report that my package mar1s doesn't pass checks any more on R 3.0.2. I started to investigate and found the following difference in multivariate time series handling in R 3.0.2 compared to R 2 (I've checked on 2.14.0). Suppose I wish to calculate seasonal component for time series. In case of multivariate time series, I wish to process each column independently.

I have done a re-working of the time series code in base R and library ts that will appear in Friday's snapshot. I am sure at least one person will be dissatisfied, but I am convinced there are fewer errors than there were before (I found more than 20, as well as several documented features that did not exist.) The principles in the code are: tsp attributes can only go on vectors of length

I don't know if this is a bug per se, but an undesired behavior in read.dcf. read.dcf takes a file argument and passes it to gzfile if it's a character: if (is.character(file)) { file <- gzfile(file) on.exit(close(file)) } This gzfile connection is passed to readLines (line #39): lines <- readLines(file) If no newline is at the end of the file, readLines

Hi, I get the following error when trying to remove a union class: > setClassUnion('a', c('matrix', 'numeric')) > removeClass('a') > sessionInfo() R version 2.15.3 (2013-03-01) Platform: i686-pc-linux-gnu (32-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8

I read the documentation below to mean that: solve_TSP( tsp_input, '2-opt', rep=99 ) will use the 2-opt method on the tsp_input variable 99 times. Catch: I get an "unused input" error. Q: Am I reading the docs (Item 1, below) correctly or is this a problem with solve_TSP ignoring its inputs (Item 2, below). Item 1: solve_TSP doc: > library(TSP) >

Hi all, I used `gzfile` and `gzcon` to read a compressed file but I found that `gzcon` gave me a different result than `gzfile`. It seems like the `gzcon` does not handle the data correctly. I have posted an example below. In the example, a portion of a compressed file is downloaded from Google Cloud as a raw vector, and the data is saved into a temp file. If I use ` gzfile` to read the file, it

Hi, I'm running into more issues when reading data from a gzfile connection. If I read the data sequentially with successive calls to readBin(), the data I get looks ok. But if I call seek() between the successive calls to readBin(), I get corrupted data. Here is a (hopefully) reproducible example. See my sessionInfo() at the end (I'm not on Windows, where, according to the man page,

I have a suggestion for kernapply for ts objects. When we choose the option circular=F, the returned series don't have the correct dates. The removed dates are all at the beginning instead of half at the beginning and half at the end. It is particularly useful when we need to smooth the series (or remove a trend using a filter) before estimating a model (like in macroeconomics) or simply

Hi, I am a total newbie to R. I am using R (2.4.1) on Mac OS X 10.4.8 and trying to install some packages using GUI Packages & Data/Package Installer interface...

Hi, I get an "internal error" when calling seek() twice on a gzfile connection. Create a gzip file: bigraw <- sample(charToRaw("abcdef"), 30000000, replace=TRUE) save(bigraw, file="bigraw.rda") Open it: con <- gzfile("bigraw.rda", "rb") Then: > seek(con, where=1) [1] 0 > seek(con, where=24980000) [1] 1

Would it be possible to get that file or a representative subset of it somewhere so that I can reproduce this?

If value is NULL I think tsp assignment should not return a class ts object. Below is a fixed version. Paul Gilbert ____ "tsp<-" <-function(x, value) {if (is.null(value)) {attr(x, "tsp") <- value if(inherits(x,"ts")) class(x) <- NULL return(x) } attr(x, "tsp") <- value class(x) <- "ts" x }
