Hi list, I'm performing a series of confirmatory factor analysis on different groupings of items from data collected with questionnaires. There are some missing values. For those sets with no missing values I call factanal(datamatrix,factors=n) where datamatrix is a table of all observations for the items under investigation. This call fails when there are missing values. help(factanal)

Hi, I am trying to read a SAS version 9.1.3 SAS dataset into R (to preserve the SAS labels), but am unable to do so (I have read in a CSV version). I first created a transport file using the SAS code: libname ces2 'D:\CES Analysis\Data'; filename transp 'D:\CES Analysis\Data\fadata.xpt'; /* create a transport file - R cannot read file created by proc cport */ proc

Hi, I could try latest 7zip (4.57) on a triple boot machine (Debian SID i386, x86_64 and native Windows XP SP2), and found something surprising in the results : amd64 at 2400MHz linux32 -> 1814 linux64 -> 1946 win32 -> 2004 So performance is much better in Linux 64 bit than in 32 bit, while both are slower than native windows system. Is it normal, I mean does anyone else obtain

R-users, Has anyone implemented (coded) the Rai and Van Ryzin dose-response model from their 1985 Biometrics paper. I'm trying to avoid re-inventing the wheel. If not any hints on coding this would be greatly appreciated. Thanks, -- ==================== Calvin L. Williams, Ph.D. ==================== Department of Mathematical Sciences, Clemson University

Dear colleagues, I'm using R64 (2.13) on Mac OS 10.6.8 and I've encountered a problem with the recode function in Rcommander. The application cannot deal with apostrpohes ( ' ) do not. I've got a factor from the 2008 Canada Election study (highest level of schooling) and some of the values include "Bachelor's Degree" , "Master's Degree". I've

Now I believe that I am getting the same error as I was getting last time I tried to build llvm-gcc. It may possibly be my Cygwin instillation but am not sure. makeinfo --split-size=5000000 -I ../../../src/llvm-gcc/gcc/doc -I ../../../src/ llvm-gcc/gcc/doc/include \ -o ../../../src/llvm-gcc/gcc/doc/cpp.info ../../../src/llvm-gcc/gcc/doc/cpp.texi ' in

I'm using package Matrix, which I have installed on several flavours of linux system. But on an important solaris install, I can't make it work. Initially, I thought the problem was using 'make' instead of 'gmake', but I masked around that, and still get errors. Those new errors seem to be related to 'cc' wanting some optional extras that I don't have

Hi everyone, I?m currently trying to use opus on a ST ARM (STM32F407) without any OS (bare metal). The aim of my project is to transmit voice over CAN bus. The main issue I have is that opus fail to allocate memory, the ALLOC macro always return a NULL pointer. I have sure that I have enough free space to allocate buffers. Is there anyone who already try this or have meet this issue ? Thanks

R-Users, I'm in the process of developing some notes on optimizing likelihoods for a class I'm teaching next term. Can anyone offer examples showing the optimization of a complex likelihood function that they wouldn't mind sharing using optim(). I've adapted some of the S-plus likelihood examplesfrom the ``Guide to Statistics" and the Zip example from ``Statistical Models in

Hello. I came across your response in an R forum and could use your help. I have a data set with 472 rows. I want to delete rows 416 through 472. The name of my data set is MERGE. I am an extreme R novice. How do I write a script to accomplish this? Thank you. --- Christopher H. Porter, M.A., M.Ed.

Dear colleagues, I'm working with the 2008 Canada Election Studies (http://www.queensu.ca/cora/_files/_CES/CES2008.sav.zip), trying to construct a weighted national sample using the survey package. Three weights are included in the national survey (a household weight, a provincial weight and a national weight which is a product of the first two). In the following code I removed variables with

>Hi Aaron, >have you got any help on this? Henrik, No. This is where I was stuck some months ago. I do not know makeinfo so was not able to proceed any thurther than verifying the makeinfo statement did the same thing when done on the command line. Basically I am stuck. I do not know whether it was my Cygwin configuration or something I have done or not done or whether it is a valid

Dear R helpers, I have a data set with 4 types (W, C, E & S). Now I have values for all types plus all possible combinations (the order is unimportant): W, C, WC, E, WE, CE, WCE, S, WS, CS, WCS, ES, WES, CES & WCES. Ideally I would like to represent everything in one graph and as concise as possible. Drawing 4 circles and depicting it as overlap just gives me 13 out of the 15

Bonjour, Je voudrais faire un petit programme sous R dans lequel je ferais intervenir des parametres que j'initialiserais dans R directement ou dans un fichier txt(des naturels, reels et caracteres). N'auriez vous pas des programmes deja fait qui reprennent ces techniques? De plus, je voudrais pouvoir travailler avec la distribution exp (rexp) de parametres: moyenne=1 et variance=1.

Dear R-users, I am a newbie to R so please excuse this naive question for which I couldn't seem to find online answers. I have this data frame containing a series of locations through time (x,y,z,t). I would like to compute the difference in x, y and z between t-1 and t. Sounds easy enough, but how on earth does one loop through vector elements and compute this difference? Thanks Thomas
