similar to: modulus operator gets syntax error (PR#925)

I'm trying to do a modulus operator in R-1.2.2 on Windows -- specific version: R : Copyright 2001, The R Development Core Team Version 1.2.2 Patched (2001-03-22) Here's what the R language manual says: "R contains a number of operators. They are listed in the table below. [snip] % Modulus, binary" Here's what happens on the R console: > records <- 100000 >

There seems to be a bug with var() when the argument is a vector with exactly three values of 1e30 (or close to this value). This does not happen with twice, four (or more) times this value, or another value. > var(rep(1e30, 3)) [1] 2.971056e+28 > var(rep(1.2e30, 3)) [1] 2.971056e+28 > var(rep(0.9e30, 3)) [1] 2.971056e+28 > var(rep(0.8e30, 3)) [1] 0 > var(rep(1e29, 3)) [1] 0 >

Dear All, I have two distributions which I don't their nature. I want to check whether they come from the same distribution. I know that I can use KS test however the standart function ks.test applies only the ks test for testing the difference of two samples (non-parametric). By the way the distribution are of Euclidean distances. One of observed and the other of shuffled data. Thanks, Ron

Hi, Can anybody tell me how to open new a new window for plot()? Thanks. Minghua

Hi, is there anybody knowing a possibility to produce a legend (describing the color scheme) in an image plot in R. In S-Plus this works using image.legend. Thank's in advance.

Hi, Is there a way to comment out multiple lines at once in R source code like C language's /* */ struct? This is quite useful when one is testing different sections of a source code.

Hi, If I have a CSV file which has several comments at the top, and the data start immediately after the line: @DATA Is it possible to use the scan() command to get the CSV data into R, by only reading the lines after @DATA? If so, how can I do it? Cheers, Kevin ------------------------------------------------------------------------------ /* Time is the greatest teacher, unfortunately it

Hello. I'm afraid that I'm missing something very obvious this afternoon... When I add a column to a data.frame (by assigning to a "new" column name a logical vector), I thought that I had (at least) 3 options to do so: R> j <- data.frame (x=1:2) R> j$y <- c(TRUE,FALSE) #assignment 1 R> str(j) `data.frame': 2 obs. of 2 variables: $ x: int 1 2 $ y: logi

I've created a bunch of postscript trees (post.rpart), which I subsequently edit in Adobe Acrobat 4.05 (I need additional labelling that isn't easy to add with R). After editing the labels and annotations using Acrobat, I then export the file to Adobe's .eps format so I can insert the picture into a Microsoft Word 2000 document. The .pdf file distilled from the .ps file is

Hello again! thanks to all who helped with overlay plots - v. easy in the end. Anyway, another new(ba)bee type question - the gurus will cringe I'm sure! Q. simple R function mm <- function (u) { x <- u$GDP x m <- mean(x) m } When the function is called the vector "x" does not get printed from within the function, but the mean value "m" does, why? I

Is there a modulus operator in R? Anna

try "%%" as the modulus operator and "%/%" for integer division eg 5%%2 equals 1 John Marsland > > -----Original Message----- > > From: Anna H.

I am a statistician and I come up to an interesting problem in cryptography. I would like to use R since there are some statistical procedures that I need to use. However, I run into a problem when using the modulus operator %%. I am using R 2.2.1 and when I calculate modulus for large numbers (that I need with my problem) R gives me warnings. For instance if one does: a=1:40; 8^a %% 41 one

Dear all, Now that R has OpenMP facilities, I'm trying to use it for my own package but I'm still wondering if it is safe to use random number generation within a OpenMP block. I looked at the R writing extension document both on the OpenMP and Random number generation but didn't find any information about that. Could someone tell me if it is safe or not please ? Best, Mathieu

suppose I have following complex number : a = -0.0475983+0.5364486i This number I got as an eigen value of a matrix. Now I would like to calculate the Modulus of this complex number. Is there any function for doing that?

R users, I am having a problem with the modulus operator for large numbers as follows, a <- 2 n <- 561 ## n is the first Carmichael number, so by Fermat's Little Theorem the below should equal zero. (a^(n-1) - 1) %% n [1] 2.193172e+152 ## Seems that R and Fermat disagree ## Also, 1000000000000000000 %% 11 [1] -32 This seems like a bug. Should I be avoiding integer math for large
