How to get MSS value for individual clusters.
Hi there, I am working on clustering genomic data. I am using HOPACH method for clustering. I have a query here. How can i get SS (split silhouette) value for individual clusters. What I am getting as MSS value, is Mean of all SS value of individual cluster. Hence I am getting single value for a gene set. But I would be very helpful for me if I get silhouette value for individual clusters.

Distance between a vector and matrix rows
I am trying to find the distance between a vector and each row of a dataframe. I am using the function "distancevector" in the package "hopach" as follows: mydata<-as.data.frame(matrix(c(1,1,1,1,0,1,1,1,1,0),nrow=2)) V1 V2 V3 V4 V5 1 1 1 0 1 1 2 1 1 1 1 0 vec <- c(1,1,1,1,1) d2<-distancevector(mydata,vec,d="euclid") The Euclidean distance

newbie: new_data_frame <- selected set of rows
Hello, this is probably trivial but I failed to find this particular snippet of code. What I got: my_dataframe (contains say a 40k rows and 4 columns) distances (vector with euclidean distances between a query vector and each of the rows of my_dataframe) What I do: after scaling data my_dataframe I calculate distances. order them then extract top five hits my_dataframe <-

problem with the assignment function
Hello, I run into the most weird problem I have ever met. I wrote a function "rhopair", which calls a .C function. I cannot assign its value to a variable using either "=" nor "<-". After I did the assignment, "rhopair" cannot reproduce the same result as before with the same argument. Here is the code and results: >

persp and greek symbols in the axes labels
Hello, I am plotting a 3D function using persp and I would like to use greek symbols in the axes labels. I have found examples like this one on the web: plot(0,0,xlab=expression(kappa[lambda]),ylab=substitute(paste(phi,"=",true,sigma),list(true=5))) this works well with plot but not with persp: with the command persp(M,theta = -20,phi =

Help in HMM commands
Respected Sir, I am working on Hidden Markov Models for count data. My data consist of number of new infectives in a ward per month. I have data for about 50 months. How can I fit a Hidden Markon Model to my data. I am using 'repeated' package('hidden' and 'chidden' arguments). I would like to know how can I estimate the initial values of the parameters(mu and

Hi there, I notice that some of the clustering methods in R are not appropriate to deal with large data set. Here is the list I make to see which are appropriate or which are not appropriate for large dataset. Could you please take a look and check if it is right or not? I need this information to decide which methods I should choose. Thank you! P.S.: List: Appropriate for large

rJava and matrices
Hi list, I'm wanting to use a matrix as input to some java code, but I seem to be unable to do this (See code below). When searching online for a solution I found that rJava 0.5-2 (the version under development not yet in CRAN) is adding "direct support for raw vectors as method parameters". Is this related? I also tried to use .jarray / .jcast in various combinations to no avail.

Trouble creating and adjacency matrix
Hello all, I'm having trouble creating an adjacency matrix. Basically, I need to turn the following distance matrix into an adjacency matrix based on whether values are >1.5 or not. If they are >1.5, then the returned value should be 0. If they are =<1.5, then the returned value should be 1. DistanceMatrix: A B C D E [1,]

[LLVMdev] Finding Merge nodes in CFG (ambika@cse.iitb.ac.in)
hi ambika, I am not sure about this solution as i just started working in this field. How about taking analogy of a problem which ask us to find nearest common parent of two nodes in a tree.

trouble installing building packages from source using R 2.6.0 on Ubuntu Gutsy AMD64
I have recently upgraded to Ubuntu Gutsy and, for the first time, am using a 64-bit installation. After failing miserably to install R from source, not a problem for me in the past with a 32-bit install, I went the route of using the Debian Etch build. This went smoothly, but I am unable to update my numerous R and BioConductor packages, getting non-zero exit status errors on each package. Is
