similar to: problem with plots with short example.

There is a thread on this topic already: http://finzi.psych.upenn.edu/Rhelp10/2010-August/250934.html I'm rather mystified by a similar problem and wondering whether I've overlooked something obvious. I'm running with latest versions of R and all packages, and latest version of JAGS running under Windows 7. Here's the problem. I have some source code. It's given below -

I define priors in jags within r using a gamma distribution. I would like to control the shape but I have problems. Any help will be usefull. From help of dgamma ___________________ The Gamma distribution with parameters shape = a and scale = s has density f(x)= 1/(s^a Gamma(a)) x^(a-1) e^-(x/s) and rate=1/scale From jags user manual ____________________ dgamma(r, mu) has a density of

Hello, In WinBUGS 1.4 manual (http://www.mrc-bsu.cam.ac.uk/bugs/winbugs/manual14.pdf), the gamma density is presented as dgamma(r,mu) where r and mu are the shape and rate parameters, respectively. In JAGS (rjags) manual version 1.0.2, May 9, 2008 (http://www-fis.iarc.fr/~martyn/software/jags/jags_user_manual.pdf), on page 26 the gamma density is presented as dgamma(mu,r) instead of dgamma(r,mu).

There must be a better way to select the rows after 22-Apr-2004 and before 01-Sep-2004 with a temperature below 65 than this: > before2sw1 <- subset(energy.data, as.Date(start, format="%d-%b-%y") < as.Date("01-Sep-04", format = "%d-%b-%y")) > before2sw2 <- subset(before2sw1, as.Date(start, format="%d-%b-%y") >=

I've been working with R for all of about 8 hours, so anyone with more experience than this should be able to help me. General comments about my methods of work are also welcomed.

Dear all, I have a question regarding using JAGS and R. My problem is that every single time I want to call JAGS from R the latter crashes (i.e. it turns pale and the Windows tells me "R has stopped working". Strangely, if there is a mistake in my jags code, this will be reported without a crash. Only when the code is right and the model should start to run, R stops working. I already

How can I reproduce this graph in ggplot2 (regression lines and data point superimposed). Thanks, Juliet filename="http://personality-project.org/r/datasets/heating.txt" heating=read.table(filename,header=TRUE) symb=c(19,25,3,23) colors=c("black","red","green","blue")

Dearl list, can anyone point me to a function or library that can create a graph similar to the one in the following powerpoint presentation? http://bmi.osu.edu/~khuang/IBGP705/BMI705-Lecture7.ppt (pages 36-37) In order to try to explain the graph, the way I see it in R terms is something like this: the "p-q" axis is a vector of positions (for example, seq(0,5000000,1)) the

I'm new to bugs, so please bear with me. Can someone tell me if the following two models are doing the same thing? The reason I ask is that with the same data, the first (based on 4 separate coeffs a1--a4) takes about 50 secs, while the second (based on a vectorized form, a[]) takes about 300. The means are about the same, though R-hat's in the second version are quite a bit better.

Hello, I am trying to install rjags on R 3.0.0 that is running on CentOS 6.4. Jags is installed and seems to be working correctly. I get the following error when trying to install from source or CRAN, configure: error: "Problem with header file /usr/include/JAGS/Console.h " See `config.log' for more details JAGS was intalled with an rpm. Does not look like the rpm included

Hi, With the sid package jags (2.0.0-1) and r-base-core (2.11.0-1), I cannot install package rjags anymore (this used to work at some point; can't recall exactly at what R/JAGS versions): ---<--------------------cut here---------------start------------------->--- R> install.packages("rjags", configure.args="--with-jags-modules=/usr/lib/JAGS/modules-2.0.0")

Hallo! I want to use the package bayesmix. Trying the examples I had no success. The reason is, I think: > haveJAGS() [1] FALSE Have read of JAGS executable (I could not find JAGS.exe in my R directory). What is JAGS? Where can I find or download it? Karl

Greetings, I wonder if anyone can offer any help or advice--even direction to an appropriate source of advice. I am trying to install rjags 1.0.1 on Mac OS X 10.5 (see http://www-fis.iarc.fr/~martyn/software/jags/). I have R.app 2.6.1 installed. JAGS 1.0.1 is apparently successfully installed. I (think I) know this because when I type 'jags' into Terminal, I get the following:

Hi All: I get the following error when trying to install the rjags package. I've installed the jags software and I'm using Fedora 10.0 and my sessionInfo is at the bottom of this email. I'm also sorry if this email ends up having control A's all over it. I still haven't figured how to fix that. Thanks. [1] "LOADING MASS LIBRARY" checking for

Hello folks Earlier versions of jags and rjags installed on my system without any difficulty, but I'm having trouble with jags version 4.3.0-1ubuntu2~ubuntu14.04.1~ppa1 (from Michael Rutter's R ppa) and rjags version 4.6. The call to install.packages() I always used successfully now produces the error "cannot link to JAGS library in /usr/lib/x86_64-linux-gnu."? shown below

May I request that Dirk's package for jags be added to the CRAN archives for Debian and Ubuntu? Installing the rjags package for R requires specific versions of jags to be present on the system. The current version of rjags requires jags version 2.2.0 or later but the version on the Ubuntu archives at Canonical (i.e. not the CRAN archives) is 2.1.0-2 I can always install Dirk's package
