R newbie configuration
...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 = "c:documents and settings/mleeds" = $HOME. Put things in $HOME/.Rprofile that are more generic on startup and not specific to any particular R project. Put various .First() functions in the working directories of the particular projects that they are associated with so that they loaded in when their .RData directory gets...

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

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

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.

newbie R question
I'm sorry to bother everyone with a stupid question but, when I am at an R prompt in Windows, is there a way to see what packages you already have installed from the R site so that you can just do library(name_of_package) and it will work. I've looked at help etc but I can't find a command like this. Maybe there isn't one which is fine.

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

brown, durbin , evans ( 1975 )
Does anyone know where I can get R code for plotting the Brown , Durbin and Evans cumsum procedure ( 1975 ) ? I wrote my own code but I am a little worried that my confiodence bands may not be correct ( I find the formula in the original paper confusing and S+Finmetrics has a formula but that formula implies that there should be 4 lines as far as I can tell ) so I would like to see someone

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

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

newbie where to look question
I don't want to bother anyone with specific questions because I am a R newbie and I see that there is TON ( emphasis on Ton ) of documentation out there but could someone just tell me the best placed to look/read for learning about ( for R-2-2.1 in Windows ) .Rprofile .REnviron. .Rdata .First function ( analogous to the one in Splus ). Analog of Splus Chapter Basically, I want to
