signif() is primitive in 2.6.x, and so uses positional matching (almost all primitives do). See the NEWS file for the announcement of the change.

Dear Ben, If you take a look at the definition of signif() in R 2.6.1 and, e.g., in R 2.5.1 you'll see the source of the problem: R 2.6.1: > signif function (x, digits = 6) .Primitive("signif") R 2.5.1: > signif function (x, digits = 6) .Internal(signif(x, digits)) <environment: namespace:base> >From ?Primitive: "The advantage of .Primitive over .Internal

However, my understanding (perhaps mistaken) was that it should

Hello. This question concerns the Methods package. I have created a new class and am trying to set a method for it for S4 group generic "Summary". I have run into some signature problems. An example: > setClass("track", representation(x="numeric", y="character")) [1] "track" > setGeneric("max", group="Summary")

...s, ie 'double fprec is used by 'signif (not round) 'double fround' is used by 'round' (not signif) as I just found out by trying to unit-test wrappers just added to Rcpp. Sources seem to agree -- src/main/arithmetic.c has case 10001: return Math2(args, fround);/* round(), src/nmath/fround.c */ case 10004: return Math2(args, fprec); /* signif(), src/nmath/fprec.c */ So with that I suggest to alter the R-exts.texi as the patch below does.

...res: x target "foo" defined "foo" If I set a method directly for the members of "Summary" (e.g. min), the new function is still not dispatched. Of the group generics listed in ?Summary, Arith, Compare, Ops, and Complex work for me, and I cannot get Math, Math2 or Summary to work. I presume I'm probably missing something, but am at a loss. I would appreciate any pointers as to what I am doing wrong. I have run into this problem on both Linux/R 2.0.1, and Windows/R 2.0.0 (will upgrade soon!).

Dear all, I need to re-define some mathematical operators (+, *, /, etc) for an S4 class based on array. All references I have found (S Programming, Green Book) show how to define S3 methods for this (like in page 89 of S Programming for "-.polynomial"). What is the preferred S4 way for doing this? I hope I haven't missed some obvious piece of documentation. Many thanks, Iago

I was wondering how do I actually see what's inside a function, say, density of t distribution, dt()? I know for some, I can type the function name inside R and the code will be displayed. But for dt(), I get > dt function (x, df, ncp, log = FALSE) { if (missing(ncp)) .Internal(dt(x, df, log)) else .Internal(dnt(x, df, ncp, log)) } <environment: namespace:stats> I

I noticed this in current intermediate patch version: > runif(0,0,4095) numeric(0) > round(runif(0,0,4095)) [1] NA I don't like it, but maybe it is the way it is supposed to be. I would prefer for it to stay numeric(0). I notice also > ceiling(runif(0,0,4095)) numeric(0) > floor(runif(0,0,4095)) numeric(0) which leads me to thing round() is not working right. I have some code

Hello all, I am trying to get a better understanding of the underlying code for the stats::dpois function in R and, specifically, what happens under the hood when it is called. I finally managed to track down the C course at: https://github.com/wch/r-source/blob/trunk/src/nmath/dpois.c. It would seem that the dpois C function is taking a double for each of the x and lambda arguments so I am a bit

Hi! Due to package maintenance I have removed some functions but forgot to update the coresponding Rd files. If R CMD check is checking for missing documentation entries why it does not check for documentation entries which tell the user about nonexisting funcitons? In my opinion checking for documentation entries that document non-existing functions is much more important than the other way

Hi I am having difficulty with setMethod(). I have a "brob" class of objects whose representation has two slots: "x" and "positive". Slot "x" (double) holds the log of a number and slot "positive" (logical) its sign. The idea is that large numbers can be handled. I'm trying to implement a log() method using an analogue of the
