Re: [Rd] S4 Method Signatures

Ah, nevermind. I realised you could have function(...) as the function signature in the setGeneric call. -- View this message in context: http://r.789695.n4.nabble.com/S4-Method-Signatures-tp2525018p2525216.html Sent from the R devel mailing list archive at Nabble.com.

[Rd] Stats not loaded? Method for as.ts() results in error

Dear list, I've got the following problem: In a package I'm trying to build, there exists a method for the function as.ts(). When checking the package, R always throws the error that it cannot find a function called as.ts. To me it seems that the package stats (home of as.ts()) is not

Re: [Rd] Weird erratic error and illogical error message, could someone explain this?

Thank you, Duncan for your answer. Indeed, I have also tcltk loaded and running, and the memory allocation problem may come from there. I'll investigate using gctorture(). For sure, I know that I need a reproducible example for further investigations. Best, Philippe

[Rd] constness in BLAS.h/dger arguments

Hi, I am writing code interfacing R's BLAS functions, and have a problem with two missing const's in the header of F77_NAME(dger) in src/include/R_ext/BLAS.h. The current definition is missing the appropriate consts for the arrays x and y, which are stated in the BLAS documentation [2] to be

Re: [Rd] Weird erratic error and illogical error message, could someone explain this?

Martin, This looks like a possible explanation. After double-check, it occurs with R 2.10.1 and 2.11.0 (not 2.11.1, as I reported in my original email). I'll upgrade R and test again. I'll report the results on Monday, since my code has to run over the week-end. Thanks, PhG On 03/09/10

[Rd] Pointer to fourteen patches to speed up R

I've continued to work on speeding up R, and now have a collection of fourteen patches, some of which speed up particular functions, and some of which reduce general interpretive overhead. The total speed improvement from these patches is substantial. It varies a lot from one R program to the

Hi Jeff, sorry for that! I found the problem in the meanwhile. But since I'm always grateful to get answers from the list, here's what happened: I have a method for as.ts() setMethod(f = as.ts, signature = Tsi, definition = function(x, ...) { Function body }) This is the error I

Re: [Rd] Incorrect formatted output after subtracting non-integer seconds from POSIXt origin

Thanks. Yes, negative POSIX time would correspond to dates prior to 1970-1-1, or to dates prior to a more recent origin that borrows functionality from the POSIXt class: as.POSIXct(-.5, origin=as.POSIXct(2011-1-1)). If negative POSIX time is supposed to work then it's a bug in as.POSIXlt().
