I have a set of functions: Probability <- function(N, f, w, b, l, n, q) { #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that have the antigen #w is time in terms of hours #b is the starting position (somewhere in the node or somewhere in the gap between nodes. It is a number between 1 and (x+t)) #q is the length of the time step #l is the LN

Hello again, Another problem with my new CentOS 6 installation: The C/C++ support in Eclipse seems to be partial or missing - even though eclipse-cdt is installed. Eclipse starts all right, and I get a C/C++ perspective, but: 1. If I open a C++ file, it's sent to an external editor. 2. C or C++ is not mentioned in Preferences. 3. I can't find a reference to CDT under Help->About

All, I''m populating a view with checkboxes in a list. I want to be able to assign to my has_many relationship using the post values of these checkboxes. Essentially, I want to populate the relationship table which will create the correct join values in my model. Here is my check_box_tag code: <%= check_box_tag("@current_job[target_list_ids][]",

I'm stuck, but am sure it can be done I just don't understand how. I have data in an irregular timeseries. I want to be able to use stl to visualise the data (see seasonal parts etc), so I need to change to regular series of class ts (I think). I am using 2 zoo objects one is regular and the other is my irregular data. I am then merging to create the object I want but when I try to change

According to the manual, system() splits output lines into 8096-char chunks; under UNIX, actually seems to return 8094 chars, and drop the 8095th. Spot missing digits in: x2 <- system("perl -e 'print \"0123456789\"x10000'", intern=T) Looks like a bug in the code to remove newlines at src/unix/sys-unix.c:218 -- fgets() reads size-1 characters and adds

hello, i am so glad to write you. i am dealing now with writing my M.Sc in Applied Statistics thesis, titled " Data Mining Classifiers and Predictive Models Validation and Evaluation".

Hi. My VB program run a R - script located in the server with R DCOM server. The R - script is designed to send a query to DB through ODBC. There is NOT any problem when I run each code from R-window interface. However, when I call the R-script from my VB program it stucked after calling "sqlQuery" statement. I can check that odbcConnect(dsn, uid, pwd) returns -1.

Hi Timo, Periodic segfaults with doveadm proxy list: root at director1:~) doveadm proxy list doveadm(root): Error: LIST failed: Disconnected Segmentation fault (core dumped) Sometimes it's just the 'LIST failed' error, other times it's the error with the segfault. Usually the first attempt to call it works, subsequent attempts fail. I've attached a strace log of it in

Hello all, I recently discovered the "comment" command. I see it can only hold a vector of characters. Is there a way (or an alternative), to make it possible to have it keep a list? (for example, to keep different pieces of information like date of creation, information of each variable and so on) The closest solution I can think of is using 'names' on the vector, like this:

Dear R-experts! I have y(x) data, dim(y) == dim(x) == c(2000, 2) I'd like to fit them with nls: fit.result <- nls ( y ~ f(x, p1, p2, p3), start = list(p1 = ... , p2 = .. , p3 = ..) ) Actually I want to fit y[,1] ~ x[,1] and y[,2] ~ x[,2] *simulaneously*, with the same parameters set {p1, p2, p3}. I tried to feed R tha above formula, R errors with:

I'm running SVM from e1071 package on a data with ~150 columns (variables) and 50000 lines of data (it takes a bit of time) for radial kernel for different gamma and cost values. I get a very large models with at least 30000 vectors and the prediction I get is not the best one. What does it mean and what could I do to ameliorate my model ? Jerzy Orlowski
