Kjetil Halvorsen mentioned a book call "S-Poetry in R". I checked with amazon.com and Barnes and Noble but they don't have it listed. Can somebody please give me the complete reference and where it can be obtained. Suggestion: Might it be possible to put a list of the most important and new literature about R, S, and S+ which has a direct bearing on R in the Documentation section

Hi, I am really new at R. Does anyone know what is the real difference of vector and array, except that many operations that expect an array does not work on a vector?

Hi,   It may be the old question. can anyone tell me how to call perl in R? thanks   Y.     [[alternative HTML version deleted]]

Which one is more efficient? x2=c() for (i in 1:length(x)) { x2=c(x2,func(x[i])) } or x2=x for (i in 1:length(x)) { x2=func(x[i]) } where func is any function?

Hi. I'm having a little difficulty with R1.5.1. To wit: (1) Can anyone explain the following behavior? > a=strptime("2002-06-01 12:15:01","%Y-%m-%d %H:%M:%S") > a [1] "2002-06-01 12:15:01" > a+0 [1] "1932-04-25 21:46:45" > a+3600 [1] "1932-04-25 22:46:45" (2) Can anyone recommend an introductory R text other than that

I am an intern in Virginia Beach and I am currently working on a project that involves converting a script of Pearl to R. The code takes one input text file and outputs six text files. If you think you can help, I will be able to provide more detailed information. Thank you for your time! Colton Hunt

Hello all - This code will run, but it bogs down my computer when I run it for finer and finer time increments and more generations. I was wondering if there is a better way to write my loops so that this wouldn't happen. Thanks! -Tyler ################# # Bifurcation diagram # Using Braaksma system of equations # We have however used a Fourier analysis # to get a forcing function

Dear R-Helpers, I am trying to bootstrap the coefficient of variation on a suite of vectors, here I provide an example using one of the vectors in my study. When I ran this script with the vector x <-c(0.625, 0.071428571, 0.133333333, 0.125, 0), it returned CV(boot) [the second one], and stderr(boot) [the second one] without problem. However, when I ran it with the vector in the

Hi R fans, I was trying to write some code in R when I realized that I was just writing a FORTRAN 77 style program in the R syntax, and hence coming nowhere near tapping the potential of R. I'm wondering what is a good reference that would help me get up to speed in programming in R (i.e., using these classes, methods, objects, accessor functions, and many other things I don't

As a complete newcomer I am attempting to learn to use R, but am finding it extremely difficult because I have not yet found an "Introduction to R". For over a week now I have monitored the R-help list, studied the R-FAQ and related documents, downloaded and run the Windows R and looked at the Help, downloaded early and late samples of the R-help archives, and searched for illuminating

any useful books for learning the R statistical software? are they pricey? and if the books recommended focus on S, how compatible will they be for someone learning R? thank you in advance for your help. P.S. specialized survey statistical procedures? Is R good at that? [[alternative HTML version deleted]]

Hello everyone. It is time to start writing more and more function and I want to read in a good reference -book ( I can buy one, especially if it is second handed :P) -online tutorial -any other guide -How functions really work in R -How to write bigger R programs -If there are local function variables. -Global ones and how to treat them -How to include function files in order to keep your all

I am new to using R and would appreciate some advice on which books to start with to get up to speed on using R. My Background: 1-C# programmer. 2-Programmed directly using IMSL (Now Visual Numerics). 3- Used in past SPSS and Statistica. I put together a list but would like to pick the "best of" and avoid redundancy. Any suggestions on these books would be helpful (i.e. too much
