Dear all Just for fun, I have just downloaded the paper mentioned below and checked it with R-1.6.1. Everything is ok with exception of Table 2b, where I get always 1 instead of 0.5: > pbinom(1e15,2e15,0.5) [1] 1 Which value should be correct?

Dear R-experts I would like to read all files from a directory, the files have names "myname0001.txt" etc. I paste the directory plus file names and use "read.delim()". My problem is that some file names are missing, so I get an error and my program stops. Is there a way to check for a null pointer analogous to C, so that I can simply skip non-existent filenames? Please do

Dear all, First I apologize for cross-posting, but I think that this could be of interest to BioC users, too. For DNA copy-number analysis I have downloaded PLASQ500K from: http://genome.dfci.harvard.edu/~tlaframb/PLASQ/ After creating sub-directories SND and STD containing 3 Sty Mapping arrays each, I tried to compute parent-specific copy number: > library(PLASQ500K) > psCN <-

Dear Ioannis Thank you very much for pointing me to meta-analysis. Although it may not solve my problem with the normalization, it gives me some other options to display the different correlation coefficients. One possibility is the use of Funnel plots, which are even available in library(rmeta). Another possibility is the use of forest-plots, as implemented in rmeta as metaplot. Sorrowly,

Dear all I apologize for cross-posting, but first it is accepted custom to thank the repliers and give a summary, and second I have still the feeling that this problem might be a general statistical problem and not necessarily related to microarrays only, but I might be wrong. First, I want to thank Robert Gentleman, Mark Kimpel and Mark Reiners for their kind replies. Robert Gentleman kindly

Hi, I have a problem executing "library(ROracle)" in R: OS/Software: Redhat 8.0, all available patches applied Oracle 9i v9.2.0.1.0 R v1.7.0 ROracle v0.5-0 DBI v0.1-5 The compilation and installation of ROracle went fine. However when I try to load ROracle I get the following: >> library(ROracle) >Error in dyn.load(x, as.logical(local), as.logical(now)) : > unable

Hey. Is ist possible to guarantee CPU Performance to virtual machines? E.g.: I have a 4 CPU host machine. 3 guests are running. Each has 2 CPU. When VM1 needs more resscources than the other 2, can i guarantee that VM1 gets the most Power of the system at this time?

Hello, I am using Dovecot 1.2.9 on a 32bit on Ubuntu 10.04.2 LTS. We got one user who uses folders in an "exessive" way. He has got 704 subscribed folders. That means about nearly 3000 folders on the filesystem. Since ~ a week the user couldn't work because of timeouts when connecting to Dovecot (IMAP). Thunderbird doesn't show any folders - timeout - the webmail System

Btw, all the pbinom() examples posted to S-news today return the proper result in R Martin >>>>> "JS" == James Stapleton <stapleton at stt.msu.edu> writes to S-news : JS> More interesting behavior of pbinom: >> pbinom(3,2,.8) JS> [1] 1 >> pbinom(30,2,.8) JS> [1] 0.9967653 >> pbinom(40,2,.8) JS> [1]

This came up due to a question from Anders Hald: Bernoulli calculated an approximation to the smallest n so that P(0.58 <= x/n <= 0.62) >= 1000/1001 What is the exact value? Now try n <- 6350:6500 Pr <- function(n)pbinom(0.62*n,n,0.6) - pbinom(0.58*n,n,0.6) + dbinom(0.58*n,n,0.6) plot(n,Pr(n),type="b") abline(h=1000/1001) min(n[Pr(n)>1000/1001]) Next, try Pr

Dear R users, I?m trying to optimize simultaneously two binomials inequalities (used in acceptance sampling) which are nonlinear solution, so there is no simple direct solution. Please, let me explain shortly the the problem and the question as following. The objective is to obtain the smallest value of 'n' (sample size) satisfying both inequalities: (1-alpha) <= pbinom(c, n, p1)

Dear R users, I have a problem computing time differences using R. I have a date that are given using the following format: 20080620.00, where the 4 first digits represent the year, the next 2 ones the month and the last 2 ones the day. I would need to compute time differences between two vectors of this given format. I tried around trying to change this format into any type of time serie

Full_Name: Chanseok Park Version: R 2.2.1 OS: RedHat EL4 Submission from: (NULL) (130.127.112.89) pbinom(any negative value, size, prob) should be zero. But I got the following results. I mean, if a negative value is close to zero, then pbinom() calculate pbinom(0, size, prob). dbinom() also behaves similarly. > pbinom( -2.220446e-22, 3,.1) [1] 0.729 > pbinom( -2.220446e-8, 3,.1)
