similar to: help with Qt and event loops

Hi, a few days back I had asked for help on a Qt device package. Thanks to hints from Duncan TL and Thomas Friedrichsmeier, I now have something more or less functional. For those interested, It can be downloaded from http://dsarkar.fhcrc.org/R/R-Qt.html I have a couple of related questions. First, dev.interactive(), used in example() and many demo()-s to decide if the current device is

Hello, I am trying to calculate and plot mean and confidence intervall for a set of data. This is the code that I am currently using: means <- sapply(data, mean, na.rm=TRUE) n <- sapply(data,length) stdev <- sqrt(sapply(data, var, na.rm=TRUE)) ciw <- qt(0.98, n) * stdev / sqrt(n) par(mgp=c(2,0.6,0), las=2, fin=c(7,3), mai=c(1,0.5,0.2,0.2), cex=0.8) plotCI(x=means, uiw=ciw,

help(qt) states that: "ncp non-centrality parameter delta; currently except for rt(), only for abs(ncp) <= 37.62" so I would expect that calling qt with non-centrality parameter exceeding 37.62 should fail, instead e.g. calling > mapply(function(x) qt(p = 0.9, df = 55, ncp = x),35:45) gives: [1] 40.21448 41.35293 42.49164 43.68862 44.82945 45.97048 47.11170 48.25310 [9]

I have tried to compile kde window decorator, but "configure" don't check my Qt installation and it don't have a option to specify the path. Thanks for your

It seems that i made some changes that make xconfig to not work .. the problem is that not matter what QTDIR i select i receive the same errors that start with : adrian at sevcenco: linux-2.6.37 $ make O=/home/adrian/kernel/kernel_out xconfig GEN /home/adrian/kernel/kernel_out/Makefile HOSTCXX scripts/kconfig/qconf.o /usr/lib64/qt4/include/Qt3Support/q3toolbar.h:45: error:

Hi, After a few modifications in the makefiles, I successfully compiled the Qt device (written by Deepayan Sirkar) for OS X 10.4.9 on a Powerbook. However when loading into R If i remove this line from zzz.R in qtutils/R grDevices::deviceIsInteractive("QT") and then install >library(qtutils) loads fine and the QT() calls returns a QT window, however, if i switch to

However for df close to 1 it seems to have problems as seen by: qt(0.5,seq(1,1.1,by=0.0001)) For example: > qt(0.5,1.01) [1] -0.2300470 Higher df as df=1.1 (and up to approx df=1.7) seem

Sorry about the html-formatted message. Here it is again in plain text. Hello, The function qt returns NaN for degrees of freedom <1. For example: > qt(0.5,0.5) [1] NaN Warning message: In qt(p, df, lower.tail, log.p) : NaNs produced But qt(0.5,0.5) should be 0, since the distribution is symmetric. > pt(0,0.5) [1] 0.5 It actually fails with any value, as long as df<1.

hi, i want to build a Qt front-end GUI which communicates with R, and i am not sure what i should use for the interface. There seems to be many ways: R.dll, Rinside, Rcpp, RQt, Rtools... . what is the best way? please advice. basically what i want to do is that, the Qt GUI will allow users to make selection and enter numbers, these inputs will be fed to R, already written .R files will perform

Hello, I am developing an application using Qt framework and C++. I want to use R as statistics engine of my application. After doing some search on internet; I came to the conclusion that RCPP, MPI with RInside is what I need. The next logical task was to quickly tryout "qtdensity" project of RInside, for understanding the build and other settings. I hit some roadblock here and got

Taking a look ahead at your QT (OSX version) work, you have Theora Encoding and Decoding on the list. This could be very beneficial as many times the only way to get a constant frame-rate out of QT is to export (and for DV video recorded in QT, this can be a large issue). Another major issue is that the video coming from DV (at least the sources I have used) is almost always

The solution post is here: http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2012-November/004771.html In the paragraph: I did need however to install Rcpp and RInside from source, and with the same compiler used to compile qtdensity (otherwise I would get additional linker errors). As I had trouble getting the (Cygwin-based) g++ shipped with Rtools to work with Qt, I used instead the

I'm using CentOS 7 for development of software that is sometimes used on Red Hat Enterprise Linux 7. I conjunction with an update of one of the applications, I asked some Red Hat users to install the Qt 4 Assistant application via the qt-assistant package (which is used by a "help" function in our software.) It seemed like there was no such package in the Red Hat package set,

Hello, Everyone. Just few notes for everyone, who wants to build Qt with llvm. Everything was tested with shiny-new Qt 4.2.2 (X11 version) and llvm-gcc4 & LLVM from head. Instructions written here should also work on 1.9 release, as I've tested Qt build last time just before 1.9 release. 1. Specs Qt uses it's own configuration and build system called "qmake". We should

I have C5 64-bit running on my laptop and am trying to get k3b 1.0.3 compiled from source. It keeps complaining about qt not being installed or available. I performed a yum install of everything qt, but it still complains. I've read some postings on various web pages about creating symlinks, but although tried, that still didn't fix any problems. What am I missing? Thhanks. Scott

Is this application meant to be commercial? If so, R's open source license probably would forbid you to use it. I defer to those with real legal knowledge on this point, but you should check it. If it is not meant to be commercial, then ignore -- I have nothing useful to offer you. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and

If you adhere to the terms of the license for R you should be okay legally. If you use contributed packages they may have additional requirements. However, these terms are often overlooked by programmers targeting Windows, hence Bert's caution.
