R newbie example code question
Sometimes I print out a package and read about it and there are sometimes nice examples that I would like to run myself. Is there a way to bring them into R from the package or are they only meant to be typed in manually ? If manual is the only way, that's fine. I was just checking whether there was a quicker way. Thanks. Mark

a series of 1's and -1's
Does anyone know of a simple test in any R package that given a series of negative ones and positive ones ( no other values are possible in the series ) returns a test of whether the series is random or not. ( a test at each point would be good but I can use the apply function to implement that ) ? thanks.

R newbie configuration
I think I did enough reading on my Own about startup ( part of the morning And most of this afternoon ) to not feel uncomfortable asking for confirmation of my understanding of this startup stuff. Obviously, the startup process is more complicated Than below but, for my R newbie purposes, It seems like I can think of the startup process as follows : Suppose my home directory =

.Rprofile files (was R newbie configuration)
Thanks a lot. setHook is Currently not in my knowledge set But it's great to save these Thing so I can look them up When I feel more comfortable. Just to add to that Stata versus R discussion : I believe, anyone who uses any other package than R, is probably missing out in the long run. It's truly unbelievable what has been done here. I feel like I fell asleep for 5 years ( by not using

FW: R and read.irts
I have never worked with R before so I am sorry if this is a bad question but I've tried and tried ( all day ) and I can't figure this problem out. I have the code below and I included the data file as an attachment. The code works in term of reading in the data correctly but when the graph gets created, the xaxis is really strangely/incorrectly labelled. I have been trying to understand

I think simple R question
I have a vector x with #'s ( 1 or -1 in them ) in it and I want to "mark" a new vector with the sign of the value of the a streak of H where H = some number ( at the next spot in the vector ) So, say H was equal to 3 and I had a vector of [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] 1 -1 1 1 1 -1 1 1 -1 -1 then, I would want a function to

I think not so hard question
I'm sorry to bother this list so much But I haven't programmed in A while and I'm struggling. I have a vector in R of 1's and -1's And I want to use a streak of size Y To predict that the same value will Be next. So, suppose Y = 3. Then, if there is a streak of three ones in a row, then I will predict that the next value is a 1. But, if there is a streak of 3 -1's in

newbie where to look question

ESS and Emacs
I have been using the document written by John Fox titled Sn Introduction to ESS + XEmacs for Windows Users of R. It's a very nice document and I went through it carefully but I got an error when I finished it and launched XEmacs. The error is "cannot open load file : ess-site". So, I did more investigation and it seems like there is a folder Program

Using R in a production /real time windows environment
I just had a question for anyone who has done this. I am currently using R in a research environment but I was wondering if anyone has had experience using it in a production/real time environment where data is coming in quite quickly ( every second or so ) and things have to be calculated quickly and sent back out to some kind of front end.GUI environment Was this successful or difficult and

complex matrix manipulation question
I've done stuff like this before but it's been a while and I'm stuck. Suppose I have a matrix with one column x and another column y and both are numeric and let the row index of the matrix be i Starting at index i ( i would equal on the first iteration ) when the cumulative sum of x_i+1 - x_i is greater than W = some constant, I want to mark that spot in the row, call it i^* and

Rd2dvi - script (PR#1029)
Full_Name: Ole Christensen Version: 1.3.0 OS: Solaris Submission from: (NULL) (130.225.48.2) I have discovered a problem with script Rd2dvi for R-1.3.0 on our Solaris machines. When writing R CMD Rd2dvi Name_of_Package, then things go wrong with the conversion to Latex of the DESCRIPTION file in the package. Having discussed the problem with our system administrator, he constructed a script

customising installed libraries
hello I am returning to some libraries that I had previously customised by amongst other things adding additional functions. I had simply typed these new functions into the file in library/R/thelibrary. These however do not seem to be loaded now as they previously were under older versions of R. What's changed and what do i need to do? Thanks Stephen

(not necessarily R-related) help with data presentation
I have a question which is not necessarily related to R. I want to use a distorted political map of the world with certain countries increased in size according to a certain variable (an idea similar to the homunculi usually found in psychology textbooks) to demonstrate the coverage of particular countries in a news service. Does anyone have any idea of how to approach this? I don't think

Fonts do not display properly on Red Hat
Hi I'm using R version 2.3.1 on Red Hat Enterprise Server 3. When I run a simple: plot(1:10,1:10) The plot comes out great, but the fonts are displayed wrongly: http://coxpress.sourceforge.net/test.jpg I realise this is probably not an R problem per se, but before I go messing about with my fonts, can someone tell me which fonts R (or X11) is trying to display, where they might be

Installing a package yet it will not work.
I want R to read my Microsoft Access database or maybe even a Sybase database. I installed RODBC or at least thought I did.
