Hi, I don't understand the following. When I create a small artificial set of date information in class POSIXct, I can calculate the mean and the median: a = as.POSIXct(Sys.time()) a = a + 60*0:10; a [1] "2009-03-10 11:30:16 EDT" "2009-03-10 11:31:16 EDT" "2009-03-10 11:32:16 EDT" [4] "2009-03-10 11:33:16 EDT" "2009-03-10 11:34:16

Dear R users, I need to reorder a dataframe using 3 variables for the determine the sorting order. When I create a simple dataframe to test the method, things work as I expected: a1 <- rep(1:10, each=8) a2 <- rep(rep(1:2, each=4), 10) a3 <- rep(c(1:4),20) (a <- data.frame(a1, a2, a3)) for each combination of a1 and a2, a3 is increasing t <- order(a$a1, a$a2, rev(a$a3)) b

Hi, I cannot make a reproducible example easily for my problem, so I'll describe it as best as I can. I merged 2 dataframes but was surprised when one line on the x dataframe did not get a match in the y dataframe, because I knew such a match existed. There was only one "by" variable in the merge, in Date format: in x: $ p?riode : Date, format: "2009-06-09"

Hi, people. I met a little problem for which someone might have a solution. Let's say I have an executable file (named "pp.R") with this contents: #!/usr/bin/Rscript options(echo=TRUE) a <- 1 Sys.sleep(3) a <- 2 If I execute "./pp.R" at the shell prompt, the output shows the timely progress of the script as expected. If I use "./pp.R | tee

Dear developeRs, Compilation of the latest version (0.9-5) of my actuar package fails with r-release MacOS_X ix86 on CRAN; see http://www.R-project.org/nosvn/R.check/r-release-macosx-ix86/actuar-00check.html All errors come from accented letters in comments in latin-1 encoded files (except hierarc.R which is in UTF-8, my bad). Encoding is declared as latin-1 in DESCRIPTION. The package

Hi, people. The output produced by "?options" contains: 'expressions': sets a limit on the number of nested expressions that will be evaluated. Valid values are 25...500000 with default 1000. [...] and a bit further down: The 'factory-fresh' default settings of some of these options are [...] 'expressions'

Hi, people. Executing the following command: hist(rpois(100,5), labels=TRUE) yields a graphic in which some labels are truncated (on an X11 device). The truncated labels are those over the highest bars. The hist function should ideally manage enough room for the labels, automatically. (Specifying ylim solves my problem, but yet, hist could be frienlier.) --please do not edit the

Hello, I use: R version 2.9.2 (2009-08-24) Copyright (C) 2009 The R Foundation for Statistical Computing ISBN 3-900051-07-0 on Ubuntu 9.10, I usually run R from ESS (5.4 on current Unbuntu) from Emacs-22.2.1. But I also tried the following from the console and it gave the same results. I have a data file containing lots of European characters, French, German, Italian and so on. I can read it

Hi, R friends. I had some difficulty with the following code: qqnorm(freq, log='y') qqline(freq) as the line drawn was seemingly random. The exact data I used appears below. After wandering a bit within the source code for "abline", I figured out I should rather write: qqnorm(freq, log='y') par(ylog=FALSE) qqline(log10(freq)) par(ylog=TRUE)

Hi, what to do with this? thanks in advance [serge@rex serge]$ wine write.exe Invoking /opt/wine/bin/wine.bin write.exe ... For language 'fr' several language ids were found: fr_FR - 040C; fr_BE - 080C; fr_CA - 0C0C; fr_CH - 100C; fr_LU - 140C; Instead of using first in the list, suggest to define your LANG environment variable like this: LANG=fr_FR Wine exited with a successful status

Hi, people. ?alist says: 'alist' is like 'list', except in the handling of tagged arguments with no value. As written, this description is misleading. For example: > list(e=3+5) $e [1] 8 > alist(e=3+5) $e 3 + 5 We are not in the situation of tagged arguments with no value, and then, clearly, 'list' and 'alist' behave

Hi, R people. Consider the following small R session: ======================================================================> > a <- c(8.48, 9.58, 9.96) > stem(a) The decimal point is at the | 8 | 8 | 5 9 | 9 | 6 10 | 0 > stem(round(a,1)) The decimal point is at the | 8 | 5 9 | 9 | 6 10 | 0

Hi, Can we attach a more descriptive "label" (I may use the wrong terminology, which would explain why I found nothing on the FAQ) to variable names, and later have an easy way to switch to these labels in plots? I fear this is not possible and one must enter this by hand as ylab and xlab when making plots. Thanks in advance, Denis Chabot

I noticed that R scripts produce a spurious white line after output. For example, the following shell script, #!/bin/sh R --slave --vanilla <<EOF cat("Hello\n") EOF when made executable under the name ``hello`` along the search path, behaves like this: $ hello | od -bc 0000000 110 145 154 154 157 012 012 H e l l o \n \n 0000007 The second newline is

I tried this with the quartz() and pdf() output devices. Only a single output device is created by the process and is repeatedly overwritten by plot(). Also

Hi, people. xy.coords() does not behave like its documentation says, when given some matrices. ?xy.coords says: If 'y' is 'NULL' and 'x' is a [...] formula [...] list [...] time series [...] matrix with two columns [...] In any other case, the 'x' argument is coerced to a vector and returned as *y* component [...] Now, consider this short

Hi, I'm wondering why 48 %/% 2 gives 24 but 4.8 %/% 0.2 gives 23... I'm not trying to round up here, but to find out how many times something fits into something else, and the answer should have been the same for both examples, no? On a different topic, I like the behavior of NAs better in R than in SAS (at least they are not considered the smallest value for a variable), but at the

For an historical paper I'm working on, I have some Spanish plaintext, presently in the form of a Word .doc file, http://euclid.psych.yorku.ca/SCS/Gallery/images/Private/Langren/Verdadera-spanish-stripped.doc and also some ciphered text from the same original source. The ultimate goal is to use some frequency analysis of letters and word lengths in the plaintext to help decode the
