Installing R on Xandros 3.0
Dear List, After obtaining a second-hand PC and because XP costs too much, I installed Xandros 3.0 (based on Debian) but pretty easy to use if migrating from WinXP. Does anyone know how to install R on this OS? Thank you for your time, Tom Volscho ************************************ Thomas W.

Enormous Datasets
Dear List, I have some projects where I use enormous datasets. For instance, the 5% PUMS microdata from the Census Bureau. After deleting cases I may have a dataset with 7 million+ rows and 50+ columns. Will R handle a datafile of this size? If so, how? Thank you in advance, Tom Volscho ************************************ Thomas W. Volscho Graduate Student Dept. of Sociology U-2068

Fetching a range of columns
Hello, I realize that using: x[x > 3 & x < 5] I can fetch all elements between 3 and 5. However I read in from a CSV file, and I would like to fetch all columns from within a range ( 842-2411). In teh past, I have done this to fetch just select few columns: data <- read.csv(filein, header=TRUE, nrows=320, skip=nskip) data_filter <- data[c(2,12,17)]

Multifractal detrended fluctuation analysis
Dear R-users, Has anyone written a function for multifractal detrended fluctuation analysis? The "fractal" package does mono-fractal DFA, but not multifractal as far as I can tell. The MF-DFA approach is presented in: J. W. Kantelhardt, S. Zschiegner, E. Koscielny-Bunde, S. Havlin, A. Bunde, and H. E. Stanley, "Multifractal Detrended Fluctuation Analysis of

Obtaining fitted model information
Dear list, I am brand new to R and using Dalgaard's (2002) book Introductory Statistics with R (thus, some of my terminology may be incorrect). I am fitting regression models and I want to use Hurvich and Tsai's AICC statistic to examine my regression models. This penalty can be expressed as: 2*npar * (n/(n-npar-1)). While you can obtain AIC, BIC, and logLik, I want to impose the AICC

detecting null values in a CSV file
Hello all, I have a CSV file, that is 2411 columns wide. There are certain instances in teh file, where null values are located. That is: two commas together, without anything in the middle. In a certain section, the only possible values are NULL, 0,1,and 2. I need to be able to detect these NULL's and be able to have them counted. For example, in a frequency table. How can I accomplish this?

Using MathJax in R's help system
Hi, I am doing a small experiment to test if I can use MathJax ( official site: http://www.mathjax.org ) in R's html help pages (i.e. options(help_type='html')) and it seems working with some minor modifications. The screenshot (rendered by Firefox 4.0 beta and with STIX fonts) of the help page in html format with MathJax enabled is at the following url:

Large Data Set Help
I am attempting to perform some simple data manipulation on a large data set. I have a snippet of the whole data set, and my small snippet is 2GB in CSV. Is there a way I can read my csv, select a few columns, and write it to an output file in real time? This is what I do right now to a small test file: data <- read.csv('data.csv', header = FALSE) data_filter <- data[c(1,3,4)]

variance of combinations of means - off topic
Hello, and please excuse this off-topic question, but I have not been able to find an answer elsewhere. Consider a value Z that is calculated using the product (or ratio) of two means X_mean and Y_mean: Z=X_mean*Y_mean. More generally, Z=f(X_mean, Y_mean). The standard error of Z will be a function of the standard errors of the means of X and Y. I want to calculate this se of Z. Can someone
