R ignoring quantile() in source()d file
Can anyone explain this behavior? Essentially, I've created a short file to be read in via source() that gets some descriptive information on a series of variables in a data frame. For each variable, I do three things: print('last.hc.actors') quantile(last.hc.actors,probs=seq(0,1,0.1),na.rm=T) stem(last.hc.actors) where the variable name is (in this case) last.hc.actors. All that

[OT] correspondence analysis w/ non-mutually-exclusive categories
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):

Parse error in xtabs
Greetings- Using R 1.2.2 under linux, I get the following: > l.agg<-xtabs(cbind(r.logic.interests, r.logic.morality, + r.logic.enlightened, r.logic.capacity, r.logic.mediate) + ~ grouptype, + data=gt) Error in parse(file, n, text, prompt) : parse error I know the data are structured fine, as I can use all the elements in individual xtabs()

[OT] correspondence analysis w/ non-mutually-exclusive ca tegories
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

Options to plot.mca ?
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

diagonal line through plot when using pictex()
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

rotated and/or greek mtext in pictex()?
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

Problems with installation on Debian
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

Encrypted passwords really necessary for PDC ?
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

Limits on smbclient -M?
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

Extracting elements from an reStruct
Sorry if this is obvious, but my S skills aren't great and I haven't been able to find it documented anywhere. I want to write a new function for use with lme objects; the function will simply calculate an ICC (aka "rho") for each level of a mixed-effects model. What I need for this is pretty simple: (c(var1..varn, residual)) / sum(c(var1..varn, residual)) where var1..varn

Can't load e1071
After upgrading to 1.7.0 under debian linux, I can't get e1071 working properly.

Strange problem with icons!
Check out these MSKB articles. They describe how shortcuts are resolved. In particular, the last one describes the process required to "fix" this behaviour. I had a LOT of trouble when I first set up my LAN because people had a nasty habit of sharing drive C (even I used to do this until I discovered that this is a Bad Idea). The main problem is that the shortcut includes the UNC

adddriver rpc command generates segmentation fault
Hi, I'm trying to add a printer driver to samba 2.2.7, part of the RedHat 9 distro. I have all the associated files under print$/W32X86 (I verified that they were where I thought they were from samba's POV by looking via smbclient). Below is the output from a getdriver command issued to a W2K PDC to get the names of all the required files for the particular printer: [Windows NT x86]

Hello! I have problem with mediation analysis. I can do it with function mediate, when I have one mediator. But how I can do it if I have one independent variable and one dependent variable but 4 mediators? I have try function mediations, but it dosen't work. If I use mediate 4 times, each for every mediator, is it same? I want to know what is total mediate effect for 4 mediators. t.Mete
