Hi All, Here 's what I got using dgamma function : > nu<-.2 > nu*log(nu)-log(gamma(nu))+(nu-1)*log(1)-nu*(1) [1] -2.045951 > dgamma(1,nu,nu,1) [1] 0.0801333 > dgamma(1,nu,nu,0) [1] NaN Warning message: NaNs produced in: dgamma(x, shape, scale, log) Could anyone tell me what is wrong here ? I am using R-2.4.1 on windows XP. Thanks a lot.

"&&" seems to behave strangely and gives different results from "&" e.g. in a data frame selection (regardless whether terms are bracketed)? ===========Script======================= test=data.frame(gender=c("F","M","M","F","F"),side=c("R","L","R","L","R")) test

Dear All, Is there a conmand to calculate the multiplication of the elements in a vector? For example: a=c(1,2,3,4) I want to get 1*2*3*4=24. Because the dimension of the vector is high, I want to know there is a command for this task in R? Thank you so much!

Dear List, I want to let R calculate the time (run-time) it requires to run a self-written simulation function. I tried as follows: it enables me to see the starting and finishing time points. ############################# "sim.result" <- function(nsim, ...){ Starting <- date() ... # calculations # final.result <- ... # Output for display # cat("# of Iterations used

Hi all, I have a problem on how R calculates Percentiles : Suppose I have following data set: > data1 [1] -16648185 -14463457 -14449400 -13905309 -13443436 -13234755 -12956282 -11660896 [9] -10061040 -9805005 -9789583 -9754642 -9562164 -9391709 -9212182 -9151073 [17] -9092732 -9068214 -8978151 -8943912 -8761890 -8632106 -8541580 -8501249 [25] -8234466 -8219015

Dear R-users, I haven?t found rules for logical operators. I need to select data according the following rule: Condition A & (Condition B | Condition C) How should I write it?? Is Condition A & Condition B | Condition C correct or will R execute (Condition A & Condition B) | Condition C ? Thanks for your help. Delphine Fontaine Delphine Fontaine Statistician Statistics

Hi there, I want to integrate a function over an irregular polygon. Is there any function which can implement this easily? Otherwise, I am thinking of divide the polygon into very small rectangles and use "adapt" to approximate it. Do you have any suggestions to get the fine division? Any advice is appreciated. Haiyong

Hi all, i'm trying to install JGR on linux (see bottom), but it runs into errors. The bottom of the sequence below shows "JavaJD could not be found" Any suggestion, please? $ sudo apt-get install sun-java6-jdk $ sudo update-alternatives --config java There are 5 alternatives which provide `java'.

After a long sufferance I had succeeded in installing R GUI on my Linux/SuSE system. It worked fine. Unluckily a system upgrade patch messed up my monitor so I had to reinstall SuSE 10.3 and every other application on top of it. I have R running back with text interface. I tried to get the nice R GUI up & running again. I followed all the steps to reinstall the R GUI but this time I get a

Hello Listers, I am trying to sample a vector to create a new one of sample length, witha sum equal to the sum of the initial vector: initial = 10, 30, 10 (sum=50) sample example = 5, 35, 10 (sum=50) or 25, 15, 10 (sum=50), etc ... My problem is to control the sum, so it stays constant. Any suggestions would be very helpful ! Thank you in advance, Eric

There's something (probably a lot) missing in my understanding of plotmath. The LaTeX code for what I'm trying to produce is \log(-\log(\hat R)) My (probably hopeless) attempt at it uses nested group()s: expression(plain(log) * group("(", -plain(log)*group("(", \hat(R), ")"), ")")) Can anyone do it right for me, please? Thanks, Ted. Dr E.A.

I'm looking for something like Brian Ripley's glmmPQL that will handle multinomial data. Does anyone know of anything? Thanks, Ted. -- Dr E.A.

I'll be teaching a graduate course on (the analysis of) experimental designs next year, using R. Does anyone know of a suitable textbook? (Venables and Ripley MASS Ch6 on Linear Models covers roughly the right material, but at a level that is way too difficult for my students.) Sorry if this has been asked before. I've looked through the archives and found Julian Faraway's book, but

I recently updated R on Linus/SuSE 11.1 I complained because no on-line help was available from JGR after R update. I was told to update JGR as well. How can I do that ? I installed JGR on SuSE three times in the past with different R versions.Every time it's been a nightmare. I am afraid to have to spend a whole day, maybe longer, to update JGR ... I would greatly appreciate some clear

Hello, I cannot get JGR installed. Here is what I have tried so far http://wiki.ubuntuusers.de/R 1. sudo -s # root werden R CMD javareconf root at gunnar-laptop:~# R CMD javareconf Java interpreter : /usr/bin/java Java version : 1.5.0_18 Java home path : /usr/lib/jvm/java-1.5.0-sun-1.5.0.18/jre Java compiler : /usr/bin/javac Java headers gen.: /usr/bin/javah Java archive

Dear all, I installed the amd64 cran2deb [1] JGR binaries on a fresh Debian testing, and JGR is missbehaving. When JGR starts up, one core of the CPU goes to 100% and stays there, even though I am keeping it idle and not performing any operation. I tried JGR with both sun-java6-jdk and openjdk-6-jdk, debian-liv:/home/liviu# update-alternatives --config java There are 4 choices for the alternative

Dear all, After an update from Ubuntu Edgy to Feisty, I seem to have lost package JGR()!? I have updated my sources.list to point to the Feisty repos at http://cran.ch.r-project.org/ and re-installed JGR() via: $ sudo rm -rf /usr/local/lib/R/site-packages/* $ sudo R CMD javareconf $ sudo R > install.packages("JGR",dep=TRUE) > library(JGR) > JGR() However, I get the
