similar to: argument order for Math2 group functions in R 2.6.x (PR#10683)

Full_Name: Ben Hansen Version: 2.6.1 OS: Windows Submission from: (NULL) (66.93.3.101) Hi, In R 2.6.0 or 2.6.1 on Windows, I get the following upon opening the GUI (no previous commands or special settings): > signif(digits=4, x=1/3) [1] 4 It seems to be taking 4 to be the "x" argument, the number to be rounded. However, my understanding (perhaps mistaken) was that it should

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

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")

Hi, I'm currently in the process of writing an R-installation SOP for my company. As part of that process I'm using the recommendations from the 'R Installation and Administration' document, section 3.2, "Testing an installation". This is done on an XP machine, using the latest binary of 2.11.0. The binary is downloaded and then installed from the installer. I then

I have some trouble interpreting the output from profiling. I have read the help pages Rprof, summaryRprof and consult the R extensions manual, but I still have problems understanding the output. Basically the output consist of self.time and total.time. I have the understanding that total.time is the time spent in a given function including any subcalls or child functions or whatever the

Hi everyone, I'm witnessing an odd modelling phenomenon that I can't explain. If anyone has seen this before, or can explain what's going on would let me know, I'd be very grateful! Especially if I'm just being dim. I'm fitting a pair of continuous variates and their interaction to some residuals from another model. The sequential anova statement changes with the term

signif(.) is a <primitive> function. Unfortunately, I couldn't even find WHERE in the source, signif(.) is defined. Here are the symptoms: xmin <- .Machine $ double.xmin signif(xmin,3) #--> NA umach <- unlist(.Machine)[paste("double.x", c("min","max"), sep='')] for(dig in 1:10) {cat("dig=",dig,": ");

Dear All, I try to use Sweave to make a document. But when I use the Sweave() command on it and build a pdf with pdflatex (3.141592-1.40.3) my apostrophes are replaced by some gibberish (an 'a' with a hat on it, a capital A with a arc pointing upwards on it and a capital Y with two points on it). If I manually replace the apostrophes using the keyboard, I get a different looking

I need a function like signif(), but returns the rounded values as character strings, formatted with trailing zeros where appropriate. If anyone has one, I would sure appreciate a copy. Thanks -Don Details: signif() rounds a number to a specified number of significant digits, for example: > x <- c(2.503,2.477,0.1204) > signif(x[1],3) [1] 2.5 > signif(x[2],3) [1] 2.48

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

Dear list, A while ago I found in the web a function (sadly I can't credit the author as I don't remember where I picked it up from) whose output is a dataframe that lists for every object in the global environment its class, mode, dim & length (where applicable). It is meant to be an upgrade to the ls () function with a far more informative and detailed output and it quickly became

Hello! I am trying to round the number always up - i.e., whatever the positive number is, I would like it to round it to the closest 10 that is higher than this number, the closest 100 that is higher than this number, etc. For example: x<-3241.388 signif(x,1) rounds to the closest thousand, i.e., to 3,000, but I'd like to get 4,000 instead. signif(x,2) rounds to the closest hundred,
