Hi, R people. I'm shy reporting this, as a bug in this area sounds very unlikely. Did I make my tests wrongly? I'm still flaky at all this. Let me dare nevertheless, who knows, just in case... Please don't kill me! :-) Not so long ago, I wrote to this list: > (For now, [the library code] works only for me when I do _not_ use `-l > MY/OWN/LIBDIR' at `R CMD INSTALL'

Good working knowledge of a DBMS is almost invaluable when it comes to working with very large data sets. In addition, learning SQL is piece of cake compared to learning R. On top of that, knowledge of another (SQL)

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, people. Two days ago, I sent to this list a little toy for exploring polynomiographs (yet, the mathematical formulas were not polynomials anymore, so the name is not really appropriate). After studying R calls, expressions and functions a bit more, I gave myself the homework of producing an animation out of my recent toy. The resulting animation, and also the sources, are available at:

Hi Michael, I experienced the same thing in the past. After you get the R-3.2.2.tar.gz and uncompress it, enter the R-3.2.2 directory and run the ./configure and make from there, rather than a different one. One other thing, you probably already did this, but just in case you might want to double-check this section as well: https://cran.r-project.org/doc/manuals/r-release/R-admin.html#AIX

Hi list members I have a vector of strings x=c("w","ex","ee") And I want to get a logical vector showing the positions where my search string "e" matches the elements partially, i.e. is at least the left-hand part of the target strings, i.e. I want to get a vector FALSE TRUE TRUE. Any ideas? Thanks Steve Powell proMENTE social research research |

Except for the ability to perform circular recalculation, I believe that the closest programming analogy to a spreadsheet is a functional programming language. Check out Haskell (or LISP or Erlang) to do what you describe. -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Fran?ois Pinard Sent: Wednesday, August 29, 2007

Hi, people. A tiny suggestion for the system.time function. Could the returned vector have names? These could be like: c("User", "System", "Elapsed", "Sub.User", "Sub.System") That would then produce self-documenting output. -- Fran?ois Pinard http://pinard.progiciels-bpi.ca

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

Hi, R people. In ?factor, in the "Examples:" section, we see: ## suppose you want "NA" as a level, and to allowing missing values. (x <- factor(c(1, 2, "NA"), exclude = "")) is.na(x)[2] <- TRUE x # [1] 1 <NA> NA, <NA> used because NA is a level. is.na(x) # [1] FALSE TRUE FALSE I'm a bit confused by this example, as I

Hi, people. This is about R 2.3.0 under Linux. It seems that edit() may change a function environment.

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

--KsGdsel6WgEHnImy Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Disposition: inline Content-Transfer-Encoding: 8bit Hi, people. Wandering in R archives, and seeing the message attached below, I noticed that: mapply(rep,times=1:4, MoreArgs=42) still segfaults on R 2.2.0, and thought I should be a good citizen and report it, even if I do not have an actual problem

Hi, people. Allow me to chat a tiny bit on two vectorisation-related matters, in the context of R. I'm curious about if the following ideas have ever been considered, and rejected already. First is about using the so-called Duff's device for partially unrolling loops. I did not overly check in R sources, and am not familiar with them anyway, but the only usage I saw is within

Hi, people. Within ?hist (using R 2.3.0), one reads: density: values f^(x[i]), as estimated density values. If 'all(diff(breaks) == 1)', they are the relative frequencies 'counts/n' and in general satisfy sum[i; f^(x[i]) (b[i+1]-b[i])] = 1, where b[i] = 'breaks[i]'. I trip on this explanation each time I read it. Some R guardians will be

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 to R developers. In the "Details:" section of "?levels", it would be nice including the following sentence, taken from a reply from Brian Ripley: If you set two levels to be the same label, they get merged. Granted, the "Examples:" section does have a terse comment and examples from which users may imply this behaviour. Yet, the documentation would be

Hi, people. I was a bit intrigued by the message quoted below. Indeed, if pt() is given a matrix, it returns a matrix. Should this feature be documented? ?pt speaks about "a vector of quantiles", and says nothing about the type of what it returns. The same might presumably apply to other distribution-related functions. ----- Forwarded message from Martyn Plummer <plummer at
