Hello, I am trying to do some parallel programming with R. I programmed with C and MPI before. I heard that there is a package called Rmpi and one called snow. What is the difference? I know the administrator installed snow in our system so I wonder if this mean there is Rmpi in it. I believe the Rmpi will have similar functions than MPI that is why I am specially interested in it. Thanks

Hello, When using PAM (partitioning around medoids), I would like to skip the build-step and give the fonction my own medoids. Do you know if it is possible, and how ? Thank you very much. Isabel

Hi, Is there any R library that is capable of handling polygamma function (Hurwitz zeta function also works)? I am aware of digamma(0 and trigamma(), but could not find more advanced versions. I'd appreciate any help. Hakan Demirtas

Thanks very much to all who answered my question yesterday on loops. Just a further quick question: If I have this: for(i in 1:n) { subset <- data[which(data$id==i),] which returns the rows where I have the variable ID=1, how can I tell the same statement to return just column Y where ID=i? I have tried this for(i in 1:n) { subset <- data[which(data$id==i),data$Y] but it

Hi all Perhaps someone could help me? I am running a loop from i=1 to n In my data.frame I have a list of i.d's (i=1 to n) and each i.d has 2 rows of data (representing 2 time points) e.g. id Y X1 X2 1 1 0 0 1 0 0 0 2 1 1 0 2 1 1 0 I am wanting to put into my 'for' loop, a line which can pick out the rows where id=i and call this a

Hello. The laboratory where I work has the possibility to get a Sun machine with 12 processors. My question is: can R be used to implememt parallel algorithms which take into account the several processors? Is there a way to run *threads* in R? If this is possible, would somebody share his/her experiences? Thanks. Isabel -- Isabel Cañette Iguá 4225 Centro de Matemática 11400

Hola a todos, es la primera vez que escribo a la lista, espero explicarme correctamente. Trabajo en cronobiología de mamíferos y quiero comenzar a analizar mis datos con R (haciendo análisis de varianza ya llevo unos años en el entorno). Me interesa saber si cada una de mis variables podría ajustarse a una función sinusoidal; tengo medidas cada dos horas para cada una. Querría extraer el mesor y

Hi R-people, I performed controlled experiments to evaluated the seeds germination of two palms under four levels of water treatments. I conducted a generalized linear model (GLM) with a Poisson distribution to verify whether there were significant differences in the number of seed germination (NS-count variable) between treatments and species (explanatory variables). Thus, my model and output

Hola, espero ser clara en el mensaje ya que es la primera vez que recurro a este tipo de ayudas, explico mi duda: Tengo un dataset con 4505 observaciones en el que la variable dependiente son presencias (n=97 y clasificadas como 1) y ausencias (n=4408 y clasificadas como 0). Mi primer paso fue realizar un GLM con una muestra compensada de ausencias y presencias para la variable dependiente, es

Hi all: I've got a couple Ubuntu 9.10 machines that are suffering from a recurring failure of winbind that essentially crash the machine. When the system is in the "crashed state", one can ping the system, but all forms of login fail. It will not even respond to tftpd requests; ssh connections "time out", but the initial port is opened (just no connect). Rebooting does

Hi all: I'm building an authentication infrastructure for combined windows plus linux clients. To that end, I have a Win Server 2008r2 ADS and a win svr 2008r2 client, and an ubuntu 9.10 client running the default samba + winbind (whatever is in their production repos). I had it 95% working this morning...Then all of a sudden, all winbind queries died. No idea why. I spent the entire day

Full_Name: Chanseok Park Version: 1.8.1 OS: linux-gnu Submission from: (NULL) (130.127.112.183) digamma with any negative value does not give a right answer. It gives -1.797693e+308 for any negative arguments. For example, digamma(-1.1) gives -1.797693e+308. The right answer should be 10.15416 This bug can be easily fixed by using the following digamma identity. digamma(x) = digamma(1-x) -

Hi. Sorry: my level of english is not enough good. I hope you understand what I mean. My question is: it's possible to share a subdirectory (and only one subdirectory for every user) in the section [homes]? The version of samba which i'm working is 2.2.7a, over Solaris 8. Thanks in advance. --
