Stochastic SEIR model
Dear colleagues,
I?m a new R-help user. I?ve read the advertisements about
the good manners and I hope to propose a good question.
I?m using R to build an epidemiological SEIR model based
on ODEs. The odesolve package is very useful to solve
deterministic ODE systems but I?d like to perform a
stochastic simulation based on Markov chain Montecarlo
methods. I don?t know which packages could be

replace values in a distance matrix
Hi to everybody!
I´m just a beginner in R, and I´m trying to replace values in a distance matrix with a concret condition: replace all values (elements) lower than 4.5 with value=18.
I´ve tried this, but it doesn´t work...
Dxy would be my 117 x 117 euclidean distance matrix
M18 and M4.5 would be 117 x 117 matrices:
M18<-matrix(rep(18,13689),nrow=117)

corrgram (package corrgram): how to plot multiple correlograms in the same page?
Hello,
I am trying to plot a few correlograms on the same figure, with the function corrgram() from the package corrgram. However, the function does not seem to use the base graphic system, as setting out the multiple figure layout with, e.g., par(mfrow=c(2, 2,)) does not work.
Does anybody know a workaround for this?
Many thanks in advance for any advice
best

Function nlme::lme in Ubuntu (but not Win or OS X): "Non-positive definite approximate variance-covariance"
Dear all,
I am estimating a mixed-model in Ubuntu Raring (13.04¸ amd64), with the
code:
fm0 <- lme(rt ~ run + group * stim * cond,
random=list(
subj=pdSymm(~ 1 + run),
subj=pdSymm(~ 0 + stim)),
data=mydat1)
When I check the approximate variance-covariance matrix, I get:

Repeated-measures anova with a within-subject covariate (or varying slopes random-effects?)
Dear all,
I am having quite a hard time in trying to figure out how to correctly
spell out a model in R (a repeated-measures anova with a
within-subject covariate, I guess). Even though I have read in the
posting guide that statistical advice may or may not get an answer on
this list, I decided to try it anyway, hoping not to incur in
somebody's ire for misusing the tool.

Seems wrong to me.
If you use samba 4. ( dont know if its the same for samba 3 )
Make sure you have this in smb.conf

Términos cronobiológicos (Fuera de tema, disculpadme)
Hola a tod@s:
Tengo una duda que no es relativa a R en sentido estricto, aunque sí al fin para cuya persecución he necesitado utilizar R.
Veréis: me gustaría averiguar la diferencia (si existe) entre los términos Cronobiometría y Ritmometría. ¿Alguien lo sabe o puede indicarme alguna lista de correo o referencia bibliográfica que me sirva de apoyo?. La única referencia que encontré es ésta:

[External] Re: Error in setwd(dir) when initializing R
Dear Ana
When you installed R it gave you an option to put a shortcut on the
desktop. If you did that then you can start the R GUI by clicking on it.
You may need to customise it for your preferences. Specifically it
starts R with an option cd-user-docs which I delete and I then alter the
starting option to start in the directory I want. You may have different
preferences of course.

Ayuda boxplot ggplot2
Hola a todos
Me gustaría saber si me pueden ayudar con lo siguiente.
Realicé un Boxplot usando ggplot2 para visualizar el comportamiento de dos
variables. Visualmente no se notan las diferencias porque la gráfica de la
derecha (parásitos en el abdomen) llega hasta 20 en el eje y. ¿Cómo puedo
hacer para que las dos gráficas muestren la misma escala en el eje Y, es
decir, que las dos lleguen a 60?

Fwd: I need help with an R function! Thx!
Hi! I am doing a course about the R software and I have a couple of doubts.
In one of the tasks we were asigned, we have to perform a function that
simulates a bus' trip with 25 stops. In each of those stops, between 0 and
6 people can go on board. And when the total of passengers reaches 44, no
more people can go on board.
stops <- 25
passengers <- 0

librerias para programar una interfaz grafica en R ?
Estimados, he estado mirando en la internet si es posible programar con
R una interfaz grafica para pedir el ingreso de datos por ejemplo, pero
invariablemente obtengo paginas que hablan de interfaces graficas
(rkward, rstudio, r-commander, etc) para R o de las librerias para hacer
graficos (ggpolt, lattice, etc) ... alguien me puede orientar donde

Interfaz gráfica para docencia
Si puedo dar mi opinión es que no uséis rcomander. Al final el alumno cree que usa R pero no lo usa!!!
Depende del tiempo pero si es para psicología yo usaría excell o spss. Rcomander les va a liar mas de lo debido y deja el ordenador inutilizable... Soy profe de estadistic pero aparte estoy en segundo de psicologia y la estadistica que se da es muy muy basica como para usar R.
Salutis.
