Hi r-users,   I would like to extract the data that match.  Attached is my data: I'm interested in matchind the value in column 'intg' with value in column 'rand_no' > cbind(z=z,intg=dd,rand_no = rr)             z  intg rand_no    [1,]  0.00 0.000   0.001    [2,]  0.01 0.000   0.002    [3,]  0.02 0.000   0.002    [4,]  0.03 0.000   0.003    [5,]  0.04 0.000   0.003    [6,] 

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here. My question is related to systemfit; I don't know how to get the result for the entire panel. #Reproducible script Empdata<- read.csv("/Users/ngwinuiazenui/Documents/UPLOADemp.csv") View(Empdata) install.packages("systemfit")

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'

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

Sadly you failed to set your email program to send plain text and the data is corrupted at my end. I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis. I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need

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, 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, 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

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, 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

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! This is my first babble on this list, please be kind! :-) Last Tuesday, I wrote to the (likely) Webmaster of the R site to report a little problem, but also to ask for advice about how to get a bulk copy of the mailing list archives, from 2002 to now. While I quite understand that from Tuesday to now, there has been little time, and it is only normal that I did not receive a reply

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, 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, 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)

AFAICT, this is all I need to do to get a simple example working: the <head> should have this: <%= javascript_include_tag :defaults %> My test page view should have a div with an id and the ERB like this: <%= link_to_remote ''Click Me'', :url => {:action => ''show_time'', :update => ''time_box''} %>
