Dear all, I'm attempting to plot a cubic relationship between two variables controlling for the effects of a third variable. In this short example, I'm trying to use AGE to predict CORTEX while controlling for the effects of TIV (total intracranial volume): ######################## cortex = rnorm(100, mean=0.5, sd=0.5) age = rnorm(100, mean=10, sd=2) tiv = rnorm(100, mean=1000,

My installation is R version 2.4.0 on Mac OS X version 10.4.8 (the latest release in both cases). I've recently had to restore my hard drive after a crash, and fear that this may have screwed up my Perl installation slightly. Whenever I run the read.xls function from library(gtools) I get the following errors: ###################### > file =

I've seen that this question has been asked before, in the archives, but I haven't been able to find a workable answer. This may be a failure to understand the statistics! The problem is that, while I can easily get partial correlation values out of corpcor, how do I get significance values? Surely the significance of a partial correlation between two variables isn't the

Dear colleagues, I've been searching for information on the Kaiser-Meyer-Olkin (KMO) Measure of Sampling Adequacy (MSA). This statistic is generated in SPSS and is often used to determine if a dataset is "appropriate" for factor analysis -- it's true utility seems quite low, but it seems to come up in stats classes a lot. It did in mine, and a glance through the R-help

Howdy all, Dec 19 14:24:53 dev imap(seb): Error indexing mbox file /var/mail/seb: LF not found where expected I just installed version dovecot-0.99.12.1 for the first time on FreeBSD 4.10 stable. This error occurs when I try to check my mail from a remote client and I have new messages. Here is my configuration: http://unf.be/dovecot.conf It's very close to the default install. In

I've read through many postings about principle component analysis in the R-help archives, but haven't been able to piece together the information I need. I'd like to recreate an SPSS-like experience of factor analysis using R. Here's what SPSS produces: 1. Scatterplots of all possible variable pairs, with regression lines. xyplot(my.dataframe) is perfect but for the lack of

Hi, I have a dataframe wf existing of a header with different labels and beneath the values of those labels : wf: label1 label2 ... 0,45 0,21 0,10 0,45 .... .... I have a list fl <- c("label2","label3",..) Isn't possible to use the list elements in the list in order to subtract values from the dataframe? like : wf$fl[[1]] When I do in R I get :NULL

Hello, I have Novell Netware File server. Which is mounted as /mnt/novell on one of my Linux m/c. I want to take backup of Novell Server to my Linux m/c. I need everyday backup of Novell server to be taken on Linux m/c. I don't want full backup every day but I need an incremental backup. I do not want to delete any old directory or files. I have taken script from rsync examples, and

Dear Manoj, Have found out the mistake in my script. One must create directory if he/she wants to move old files to backup directory. In my script I was not creating any new backup-dir(datewise), therefore despite of have -b --backup-dir flags it was not working. This means rsync can only create automatically new direcotry for destination but not backup-dir !!!! Am I correct? Bipin ---

I am having issues with Samba DC replication between two directly connected DCs. I don't understand what is wrong or how to fix it.

Dear all, The version of readBin() in R-devel includes a use of match(), through `%in%`, which can affect its performance significantly. By using primitives instead of the rather expensive call to match(), I reduce the time spent inside readBin() by more than 30% in some of my code (part of the tractor.base package). A simple patch that does this is given below. This passes "make

I'm pretty sure this is a resolving problem.

Dear all, I have asked before, in R-help [1], about a way to create an interactive session in which commands are taken from a file or standard input - like R CMD BATCH but additionally allowing user input - but there was no response to that question, and the workarounds that I have found (using "expect", creating a temporary .Rprofile) are ugly and problematic. With the

Dear John and others, I've been wondering about whether there's any way to indicate a "nil" reference class object, which will represent "no value", and be tested for, but not fail the internal type checking. NULL is the obvious choice (or seems so to me), but can only be used if an explicit class union is created: > Foo <- setRefClass("Foo") > Bar

Dear R users lqmm version 1.02 is now on CRAN. lqmm provides commands for estimation of linear quantile regression models with random effects. Commands for independent and count data are also available. A few bugs have been fixed since lqmm 1.0. Updates of this package are (usually) made available on https://r-forge.r-project.org/R/?group_id=1396 prior to submission to CRAN. -- Marco Geraci
