I would like R to produce some tabulated data in a graphical output. When I say tabulated data, what I mean is a table with rows and columns. This would be useful when reading in a big file, performing some analysis on it, and then wanting to display the results as a table. Something like plot(x,...) where x is a matrix For example, the result could look (approximatly) like...

I read a tab-delimited ASCII table, with a header, into R thus. Table <- read.table(FileName, header=TRUE, sep="\t"); Is there any way I can now retrieve the header. The header information is obviously there since I see it, along with the values of the first row of data, when I type Table[1, ] However, I cannot find an R function to retrieve the header information from

Dear R users, I want to group the d values in classes. If I use this script I have a problem. classes <- function(x, n){ s <- seq(0, ceiling(max(x)), by = n) factor(n*findInterval(x, s), levels = s) } z<-sapply(tapply(t$d,t$plot,function(x) classes(t$d, 4)),table) z<-cbind(z) Thank you! Initial data: nr x y d plot plotn xplot yplot 121 162 50.26989 46.230

Dear Listers: I used cronbach{psy} to evaluate the internal consistency and some set of variables gave me alpha=-1.1003, while other, alpha=-0.2; alpha=0.89; and so on. I am interested in knowing how to interpret 1. negative value 2. negative value less than -1. I also want to re-mention my previous question about how to evaluate the consistency of a set of variables and about the total

Hi all-- I am in the process of helping colleagues write up a ms in which we fit zero-inflated Poisson models. I would prefer plotting the rate ratios and 95% CI (as I've found Gelman and others convincing about plotting tables...), but our journals usually like the numbers themselves. Thus, I'm looking at a recent JAMA article in which both numbers and dotplot of RR and 95% CI are

Hi, Gordon Smyth brought the following problem to my attention. PROBLEM/"BUG": Using R v1.9.0 alpha for Windows and the latest Rtools from Brian Ripley you get the following problem trying to R CMD build a package (or a bundle); >R CMD build R.basic * checking for file 'R.basic/DESCRIPTION' ... OK * preparing 'R.basic': * checking whether 'INDEX' is

Greetings, I have a meta-analysis problem in which I have fixed effects regression coefficients (and estimated standard errors) from identical models fit to different data sets. I would like to use these results to create pooled estimated regression coefficients and estimated standard errors for these pooled coefficients. In particular, I would like to estimate the model \beta_{i} = \mu +

I'm using R on Windows v2.0.1 with the nlme package (v3.1-53) and am finding some unexpected discrepancies in the output of intervals.lme and coef.lme. I've included a toy dataset at the end, but briefly, the data are longitudinal data from couples in marital therapy. Each spouse's relationship satisfaction is measured 4 times; I've fit both linear and quadratic models to the

Hi, I'm running R v1.9.0 on WinXP Pro. I noticed that R.exe and Rterm.exe behave differently on Ctrl-C. Starting a Windows Command prompt (cmd.exe) you get from running Rterm.exe: C:\Program Files\R>rw1090\bin\Rterm.exe --vanilla --quiet > ^C > ^C > 1+1 [1] 2 > Sys.sleep(100) # Ctrl-C after a few seconds > ^C > ^C > 1+1 [1] 2 > q() C:\Program Files\R>

Background: Our research group collected data from students via the web about their drinking habits (alcohol) over the last 90 days. As you might guess, some students seem to have lost interest and completed some information but not all. Unfortunately, the survey was programmed to "pre-populate" the fields with zeroes (to make it easier for students to complete). Obviously, when

Dear All, I'm analysing a negative binomial dataset from a population-based study. Many covariates were determined on household level, so all members of a household have the same value for those covariates. In STATA, there seems to be an option for 'clustered analysis' for neg-bin regression. Does an equivalent exist for R(MASS)'s glm.nb or a comparable function? Many thanks for

I am writing to inquire about a warning message that I receive when trying to model a random slope and intercept at the second level of a 3-level model. Specifically, I am testing a 3-level model in which time (WEEK) is nested in participants (PARTICIP) and participants are nested in dyads (DYADID). The goal is to examine how an interpersonal style (CORUMTO) one week predicts changes in

Hi all-- We are planning an intervention study for adolescent alcohol use, and I am planning to use simulations based on a hurdle model (using the hurdle() function in package pscl) for sample size estimation. The simulation code and power code are below -- note that at the moment the "power" code is just returning the coefficients, as something isn't working quite right. The

Dear R Experts, I am attempting to run a mixed effects model on a within-subjects repeated measures design, but I am unsure if I am doing it properly. I was hoping that someone would be able to offer some guidance. There are 5 independent variables (subject, condition, difficulty, repetition) and 1 dependent measure (value). Condition and difficulty are fixed effects and have 3 levels each

I have build asterisk from latest CVS HEAD-05/09/05 with H323 support as described in README file. Open H.323 version v1.17.1 and PWLib v1.9.0 on Mandrake Linux 10.2 kernel-2.6.11 I tested it with following phones: -- XLite (SIP softphone) -- QMix SIP IP phone (PA168F) -- SJPhone (H323 softphone) -- QMix H323 IP phone (PA168F) -- FireFly (IAX2 softphone) Everything works fine except a problem

Hello everyone. Due to problems with libsndfile's handling of FLAC files, Mixxx is going to use libFLAC directly in v1.9.0. I'm the Windows packager and am trying to build libFLAC on Windows x64 using MSVC 2008 and the following steps that I've put together: http://mixxx.org/wiki/doku.php/build_windows_dependencies#libflac The problems I have are the following: If I try to build the

Hi, I was just looking at the "CRAN Daily Package Check Results" [http://cran.r-project.org/src/contrib/checkSummary.html], and realized there are 1000 packages on CRAN as of today (look at row 3 in the table below). Yet another quite extraordinary milestone in R history. Last updated on 2007-04-12 11:48:32 Results for installing and checking packages using the three current flavors

Hi Sean, You may find that the attached patch helps. Builds perfectly here using it.
