Hi, I have a question about how to obtain the union of several data frame rows. I'm trying to create a common key for several tests composed of different items. Here is a small scale version of the problem. These are keys for 4 different tests, not all mutually exclusive: id q1 q2 q3 q4 q5 q6 1 A C 2 B D 3 A D B 4 C D B D I would like

Hi, I have a problem in which I have test score data on students from a number of schools. In each school I have a measure of whether or not they received special programming. I am interested in the interaction between school and attendance to the programming, but in a very select set of comparisons. I'd like to cast the test as one in which students in each school who attend are

Scot, Thanks for the info. I will try your code out to verify the result, but before I do that, will your code (SAS and R) work with variable names that are longer than 8 characters long without truncating the variable name in R? Also, I wonder about using your method or the PROC EXPORT method with larger data sets. The data sets I will be working with for the most part will not be that large,

Hi, I wanted to know how to compute the correlation ratio (eta) between two variables using R. Is there any function to compute the correlation ratio. Any help will be very much appreciated. Thanks, Suman [[alternative HTML version deleted]]

I am a new user of R and would like a bit of advice. I wish to write a short program in R that I can call up when I want to run it. How do I go about storing and recalling the particular code that I write?

Scot, Thanks for the additional information. On further reflection... whether one uses SAS PROC EXPORT or uses a SAS LIBNAME yourfile XPORT 'yourpathname'; statement, an intermediate file is created in either case. As far as experience tells me now, PROC EXPORT is a far superior choice, because variable names do not get truncated and you only have to deal with reading in a simple text

Hi, I'm trying to read a file containing html markup (discussion board posts) and output the various parts of each post to an field in a record in an output file (date, author, title, body). This is a one-off job and I'm trying to use R to do it. The file looks something like this: <br><ul>Created: --- - Dr. Johnsons's article - concerns<br><p>After

Hi, I'm trying to produce 6 graphs on a single page using code I've borrowed from an example by Paul Murrell: (http://www.stat.auckland.ac.nz/~paul/RGraphics/custombase-xmastree.R). It involves placing 6 horizontal barplots on one page and adding common labels. The problem is the first graph in my figure (the one in the (1,1) position) is smaller than the other 5. A toy example is

Hello all - I am sorry if this simple question is addressed in somewhere else. But, I couldn't find it. It's been for about a week using R. . . My problem is: Reading matrix data with "scan" does not seem to allow me to incorporate matrix labels (columns, and rows). If I use read.table, I can import the lables. But, the problem is, I don't know how I make this data as

Hi all, I'm having a problem creating png images with trellis.device. I would like to create many plots with a white background using a sequence number in the file argument (i.e. "%02d"). The first plot is as expected with a white background. However, the second and all subsequent plots have a gray background. I would like all plots to have a white (or transparent)

Hi, I couldn't figure out how to use the functions from the ctest library. I'm using the r-base package that comes with debian potato. library("ctest") told me that no such package existed. I checked the CRAN, but no such package was availiable, instead I was told that it would be part of the standard installation. But functions from ctest like shapiro-wilk don't work. The

Full_Name: Scot Wilcoxon Version: 1.8.1 OS: Linux Submission from: (NULL) (209.98.144.16) return() is not documented. It should also be mentioned in the R Reference section for function(). Apparently the last result of a function is the return value from a function, except when the function is terminated with a return() with an argument.

Is there an ext3 version of this? Something in ext3 makes e2undel unable to recover unlinked inodes. I just deleted something, umounted the drive to preserve the state. I used e2undel to look for stuff to recover and it found 0 deleted files. I have been using e2undel for quite a while with great success and I know hwo to use it, but it seems to not be able to recover stuff on ext3. Is there
