Thanks a lot everyone. You've been a great help! -- View this message in context: http://www.nabble.com/Choosing-a-random-number-between-x-and-y-tp21914106p21930844.html Sent from the R help mailing list archive at Nabble.com.

Hi, Ive been trying to find a function that will allow me to pull out a number between a minimum and maximum threshold. I want a random decimal number between, for example, 0 and 0.5 or 0 and 0...

Hi, I have a huge table, approximatly 16,000 x 12,000, full of various integers. Its a tab delimited file approx 400mb in size. R takes ages to read it in (read.delim), and store it as a variable...

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...

Hi, I've been trying to run an R script, however I keep getting the error message "invalid 'ncol' value (too large or NA)" The program involves reading data from table, and manipulating it in some way. However I do...

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...

Dear All Thank you all for your fast help, the solutions that I have received are: file.exists() try() allFiles<-list.files(mydir) Best regards Christian Stratowa ============================================== Christian Stratowa, PhD Boehringer Ingelheim Austria Dept NCE Lead Discovery - Bioinformatics Dr. Boehringergasse...

Sorry, my mistake, I did not realize that image() has breaks and that heatmap() inherits from image(). However, I have the following problem, maybe I am doing something wrong. I have defined: mycol <- c("blue1","blue2","blue3","blue4","black","yellow4...

Great, thank you for the fast reply Regards Christian Stratowa ============================================== Christian Stratowa, PhD Boehringer Ingelheim Austria Dept NCE Lead Discovery - Bioinformatics Dr. Boehringergasse 5-11 A-1121 Vienna, Austria Tel.: ++43-1-80105-2470 Fax: ++43-1-80105-2683 email...

Dear expeRts Is it possible to compare correlation coefficients or to normalize different correlation coefficients? Concretely, we have the following situation: We have gene expression profiles for different tissues, where the number of samples per tissue are different, ranging from...

Dear Spencer Thank you for this extensive explanation of the problem. I was just curious. Best regards Christian ============================================== Christian Stratowa, PhD Boehringer Ingelheim Austria Dept NCE Lead Discovery - Bioinformatics Dr. Boehringergasse 5-11 A-1121 Vienna, Austria Tel.: ++43-1...

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...

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...

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...
