similar to: R ignoring quantile() in source()d file

Greetings, again. This is not strictly an R question, so please feel free to ignore it if you like. My question is about the substance of correspondence analysis. Specifically, is it appropriate to use ca on a matrix of values such that the columns and/or rows are not mutually exclusive? To be more detailed: - The standard use of ca is illustrated in the example of corresp() (from MASS):

Hello- Tired of the crashes I was experiencing with r 1.2.1 on Windows ME, I downloaded the r-1.2.1.tgz under my Debian Linux box. I untared, unzipped and then I ./configure and make as specified i the FAQ. But something went wrong...I had version 0.90 per-installed, as it comes with the normal Debian distribution and now, whenever I run R, the old version is the one that executed. Can

Greetings - In trying to do a multiple correspondence analysis, I need to coerce a data frame such that each of its columns will be a factor. Can someone offer advice on how to make this happen? I've tried this: > logic.resources.f.df<-apply(logics.resources.df, 2, factor) but: > is.factor(logic.resources.f.df$interests) [1] FALSE I've also tried individually, >

Andy, Take a look at Greenacre, Theory and Applications of Correspondence Analysis. He has many example of dealing with all sorts of data. Basically, the technique is relevant for 2-way tables -- MCA is an extenstion. It is not clear in your example whether CA is really appropriate -- you want to make an observation (if at all possible) fall in one cell, treating the others layers as

Greetings. I'm using plot.mca (from MASS) to construct some correspondence analyses of data drawn from focus-group transcripts. My question is simple albeit rather open-ended: I'm wondering what options there might be to plot.mca for tailoring the plots to my needs. The documentation to the function is somewhat sparse. Thanks- Andy Perrin

Greetings- I've got some plots I'd like to include in a LaTeX document; specifically, I'd like to include them via pictex() so I can edit some of the particulars directly. However, an odd problem is coming up: a diagonal line is drawn from bottom-left to upper-right when using pictex(). This does not happen using X11() or postscript() with the same series of commands. Any ideas why

Greetings- I'm aware that there's no documentation for pictex available easily (that is, without purchasing it). I'm wondering if someone can help me with a simple task. When generating a plot using pictex() from R, one of the commands I use is mtext("Dimension 2: L=xxxx", side=2, line=3) when using X11(), this appears vertically along the Y axis; when using pictex(), it

Greetings- Running R 2.4.0 under Debian Linux, I am getting a memory error trying to read a very large file: > library(foreign) > oldgrades.df <- read.spss('Individual grades with AI (Nov 7 2006).sav',to.data.frame=TRUE) Error: cannot allocate vector of size 10826 Kb This file is, granted, quite large: aperrin at perrin:/data0/grading$ ls -l total 630304 -r-xr-xr-x 1 aperrin

Hi, I am new to Ruby and Rails programming and am having difficulty with the following scenario... Consider the following model: class Studio < ActiveRecord::Base has_many :movies has_and_belongs_to_many :actors end class Movie < ActiveRecord::Base belongs_to :studio has_and_belongs_to_many :actors end class Actor < ActiveRecord::Base has_and_belongs_to_many :studios

I've attached a perl script that I wrote to build smbpasswd from /etc/passwd. Please note that this writes a samba-2.0 format smbpasswd file. This script will: # - create accounts that exist in /etc/passwd and not in smbpasswd # - remove accounts that exist in smbpasswd and not in /etc/passwd # - preserve existing password, flags and LCT fields in smbpasswd # - sets new account passwords to

After upgrading to 1.7.0 under debian linux, I can't get e1071 working properly. The first problem I had was that g++-3.0 was the standard compiler but wasn't installed, so I installed it. e1071 then installed correctly, but I get the following: aperrin at perrin:~/afshome/papers/authoritarian/R$ R R : Copyright 2003, The R Development Core Team Version 1.7.0 (2003-04-16) R is free

I've been trying to get plot.hclust to work with a hclust object I created and have not had much success. It seems that there is some "hidden" characteristic of a hclust object that I can't see. This is most easily seen in the following example, where plot.hclust works on one object, but when this object is "dumped" and then re-read, plot.hclust no longer works. Is

I know one of R's advantages is it's ability to index, eliminating the need for control loops to select relevant data, so I thought this problem would be easy. I can't crack it. I have looked through past postings, but nothing seems to match this problem I have a data set with one column of actors and one column of acts. I need a list that will give me a pair of actors in each row,

Greetings- We use smbclient -M to send a Message of the Day to clients every once in a while. The clients are NT4 (SP3), and the server is Samba 1.9.19-prealpha. However, the same problem appears with version 2.0.0. The issue is: once the file to be sent exceeds approximately 675 bytes (smbclient reports sending 975 bytes, presumably including some overhead), the message turns up blank on the

Add usb-ver format check to "usb-hc-create". In original file, "usb-hc-create" allows usb-ver parameter as "2/2.0/2.0aaa". In low level hc create, it only uses the integer part (that is "2"), so there is no problem. But 2/2.0/2.0aaa will be saved into VM config. After that, while doing "usb-list", it cannot handle "2.0/2.0aaa" and will

Dear R-users, I need some help concerning the plotting of dendrograms for hierarchical agglomerative clustering. The agglomeration niveau of each step should be displayed at the branches of the dendrogram. For this I need the x/y coordinates of the branch-agglomerations of the dendrogram. The y-values are known (the heights of the agglomeration), but how can I get the x-values? > mydata
