Hi all: I am a user of "JM" package. Here's the problem of "sample size". The warning is: Error in jointModel(fitLME, fitSURV_death, timeVar = "time", method = "piecewise-PH-GH") : sample sizes in the longitudinal and event processes differ. According to the suggestion of "missing data",I use the same data set(data_JM) without any

hello R: we have a two-parameter IRT simulation code. The goal is to generate a response matrix.But the "for" part doesn't run. we don't know what is wrong with it. Thanks so much~~~ I <- 10 J <- 5 response <- matrix(0, 10, 5) pij <- function(a,b,theta) { a <- rnorm(J, 0.8, 0.04) a b <- rnorm(J, 0, 1) b theta <- rnorm(I, 0,1) theta for( i in 1:I ) { for(

Dear List, Some days ago, it was posted in this list a question regarding "How to generate graphics (jpeg) files dynamically". Although it was responded, there is a particular case in which I do not find the rigth solution. My question also goes in the same direction but for the particular case of generating jpeg/bmp or png files when using xyplot (grid/lattice libraries) and the

Dear all, I’m having an awkward problem in R. When I write the command Fisher.test(school.data,workspace=2e+07), where school.data is the matrix corresponding to the data set, I get the error message: FEXACT error 7. LDSTP is too small for this problem. Try increasing the size of the workspace. Increasing the workspace: Fisher.test(school.data,workspace=1e+10), I

Dear all, I?m doing some simulation studies in order to compare the estimates (and estimated standard deviations) from the ARMA(2,1) Model with an estimator that I?ve constructed. For carrying out the simulations I created a VBA project within Excel. Now, I?m using the RExcel tool for running the R commands in the VBA project. I run 2500 simulation using the ?arima? function from R and it worked!

Hi Community, here is the problem, Linux problem (reported to work on Windows). I need to generate graphical output in any of bitmap format under the 'R CMD BATCH'. Whereas the script generating png-s works perfectly in the R session, such things as X11, png and jpeg are not usable in BATCH (they cannot be switched on by --gui-X11 etc) and X11 is prompted to be required for png.

Hello all, I'm not sure if this question is better posed to a Fedora group because I have only had this problem since I upgraded from F9 to F11, but I figured that the specialised knowledge here might help me more... I have been getting these entries in syslog since upgrading. Today for instance I got: **Unmatched Entries** dovecot: Dovecot v1.2.0 starting up (core dumps disabled): 1

Hi folks, As part of our build, the Tock project uses remap-path-prefix [1] to create a reproducible build. This means that the paths inside of built artifacts are not full source paths. When we later attempt to produce a listings file, the source mapping fails. The result is many copies of this recently merged warning [2]: llvm-objdump: warning:

Hello, I am having trouble installing the package playwith on the latest Mint "helena", running R version 2.10.1 (2009-12-14).

Hello, I'm starting using R and runned a little script. The generated graphic could be exported correctly with RGui.exe ("file -> save as -> jpeg -> etc.") But if I try to run the same script with Rterm.exe and followed by: jpeg(file="test.jpeg", quality=90) The created jpeg file is completely white without any color, do you know why ? Sum up of the script:

Dear R community, I am using densityplot (lattice package) for a large dataset and wish to print it to a jpeg (the pdf is huge). R crashes consistently.

Evening folks, I'm trying to print a series of graphs to .jpeg using a variable as the title, but run into the difficultly that I can't find a way to append the file extension to the .jpeg (in this case extensionless!) files.
