The R poisson random generator rpois appears to have a bug for theta 10 or larger. The sample mean of the pseudo variates is too small: sample mean approx theta - 0.5. I use Version 1.1.1 (August 15, 2000) Of R on a Dell OptiPlex computer with the Windows XP Professional operating system. Has this bug been fixed in later versions? (I found another reported rpois bug, but it appears to be

Hello, I am doing simulations, and I generate a list at each iteration (with three component matrices in the example below), saving the results in a list. For example, after two iterations, I have something like > str(sim.theta) List of 2 $ :List of 3 ..$ : num [1:6, 1:4] -3.67 -1.07 -2.99 -18.38 -3.26 ... ..$ : num [1:6, 1:6] -7.56 -3.14 -4.99 1.03 2.79 ... ..$ : num [1:6, 1:4]

Hi, I've lost my mind on it... I have to scatterplot two vectors, grouped by a third variable, with two different dimensions according to whether each cell line in the plot is sensitive or resistant to a given drug, and with a different color for each of 9 tissues of origin. Here's what I've done:

Dear, I wrote a code to estimate the overlap between two kernel distributions. The script must estimates the overlap among each columns of data frame. With S sampled species (columns) in my data frame, I want obtain S(S-1)/2 pairs of overlap values between species. However, the code is not well write at all (only an overlap value is produced) and I can't find the solution. To illustrate the

I have a data set for different time intervals. The data has three comment lines before data for each time interval. For each time interval there are 500 data points. I want to change the dataset such that I have the following format: t1 t2 t3 ................ 0.00208 0.00417 0.00625 ................. a1 a2 a3 ...................

Following the update this morning, NTP is failing with the same symptoms that I saw several years ago (pre-CentOS, I believe) when Anaconda mistakenly blessed my ASUS A7N8X, Athlon (CPU: AMD Athlon(tm) XP 2600+ stepping 00) based system with an SMP kernel. The symptom is that NTPD never establishes sync with a server, showing over the top jitter values. [root at mavis log]# uname -r

I searched the mailing list archives and found one post relevant to my problem, but it was not specific enough to solve my problem. I am reading in a large file of data (I believe it is in ASCII format). I have tried reading the file in as a data frame and as a list, and both methods result in unwanted levels being created which leads to problems when I try to copy or reference certain cells.

Hi all, I'm working with a bunch of large graphs, and stumbled across something useful. Probably many of you know this, but I didn't and so others might benefit. Using pch="." speeds up plotting considerably over using symbols. > x <- runif(1000000) > y <- runif(1000000) > system.time(plot(x, y, pch=".")) user system elapsed 1.042 0.030 1.077

Dear all, Does any one knows why should I get the following error message, when trying to do a simple data.frame??

Dear R-help, I am having trouble with your scatterplot3d program. For help with this problem I was directed to your address by Martin Maechler at " r-core-bounces at r-project.org." I'm also sending a CC to " r-core-owner at r-project.org" as I'm not yet certain of the proper address to use for this. I have R version 2.8.1 and have downloaded 'scatterplot3d.'

I spent a week to optimize LLD performance and just wanted to share things what I found. Also if there's anyone who have a good idea on how to make it faster, I'd like to hear. My focus is mainly on Windows, but my optimizations are generally platform neutral. I aim both single-thread and multi-thread performance. r231434 <http://reviews.llvm.org/rL231454> is a change that has the

Hello R users, For the last few days I am struggling with the following task: my data.frame: A1 A2 A3 B1 B2 B3 58.81 53.292 54.501 13.013 17.39 19.407 56.02 56.251 54.033 20.099 13.15 10.411 55.376 53.099 57.625 13.396 21.031 13.22 58.584 53.194 54.218 13.038 16.854 19.289 55.7 55.921 53.847 19.942 13.153 9.828 55.093 52.934

I made other tests. It's not a matter of Win98 versus WinXP, things change passing from tftpd32 v310beta to v3.33. This version seems to work fine, but the logs show problems.
