I have a few questions regarding the snow package: 1) Is fine-grained parallelism even possible with R/snow? (ie, one task that spawns sub-tasks to do work, with results sent back to the parent task). The example(s) only seem to be totally-independent processing (which can be done just as easily with shell-script wrappers....) 2) If so, is an example available? 3. If not, then it is still

...it is specified that the constructor will try to load the annotation. Question: 1)Am I using the right annotation file ie ³drosophila2² 2) Do I need to install it before trying to use it. 3) If so, what is the procedure Many thanks ______________________________ Marco Blanchette, Ph.D. mblanche@uclink.berkeley.edu Donald C.

Hello, I would like to simulate randomly from a multivariate normal distribution using a correlation matrix, rho. I do not have sigma. I have searched the help archive and the R documentation as well as doing a standard google search. What I have seen is that one can either use rmvnorm in the package: mvtnorm or mvrnorm in the package: MASS. I believe I read somewhere that the latter was

Dear All: I'd like to know how to sort and then index a vector of floats by several levels in R. For example >x<-rnorm(100) > MyLevels<-quantile(x,probs=c(0,.5,1)) > MyLevels 0% 50% 100% -2.11978442 -0.03770613 2.00186397 next i want to replace each x[i] in x by 1,2,3 or 4 depending on which quantile that x[i] falls. How do I do that in a

Hello all: I have a column of times in format x "16:30:00" "16:30:03" "16:59:00" etc which I need to convert into time variables and do some operations on. I do the command y<-strptime(x,"%H:%M:%S"). This executes almost istantly (for a column x of length 1000 in Windows, but in Unix, where I run my production jobs, this takes over 4 minutes. I

Hello, I saw a little discussion about this in the archives, but it was unclear to me whether someone had submitted a port to R of the Splus bagplot() function. If so, does anyone know where I could get it? Thanks. Best, Matt

G'day. I'm having a little trouble getting Gridengine 5.3 running properly on a cluster using Centos 3.3. Everything appears okay, but my jobs hang in the queue with the gridengine complaining that node is overloaded, but there is nothing (unusual) running on the node and the load is 0. Has anyone else run into similar problems? -geoff

Hi I'm observing a huge difference in the performance speed of R on Windows and Unix, even though I know that my Unix machine is much more powerful than my Win machine. In particular, any character processing task is very time consuming on Unix. strptime(x,"%H:%M:%S") is about 10 times slower on Unix for vector x of the length of ~ 500. read.table() also is very slow. is there

I keep getting these fixed-width format (FWF) data files where variables for a single subject are spread across multiple lines and each line has a different format (apparently created with SAS or SPSS). To read them I stole some stuff from `read.fwf' in base R and threw together the function included below. Please feel free to test this function with your own data and let me know of any

The following line when pasted into an R Console window causes Windows XP to flash a blue screen and then restart.
