Regarding the brilliant wiki site: http://wiki.centos.org/HowTos/Amavisd?highlight=%28Amavis%29 I faced the following issue on CentOS 6.2: "Spamassind" saves each message and its attached part in a folder in clamd accesses the folder, creates itself a temporary folder and deletes it afterwards. This was stopped by SELinux and caused the virus scan to fail. This action causes SE-Linux

Hello, Newbie question and hope you can help . I have two vector V1 and V2, where length(V2) = length of (V1) * 2; length(V1) ~ 16,000. For each member in V1, I need to compare 2 element of V2 for equality i.e. for (I in 1:length (V1)) { if ( v2[i] == v1[i] & v2[i+1]==v1[i] ){ statement_1 statement_2 . } } This for-loop is too slow

Hi, I place a t.test in a loop and would like to continue to process the loop even when t.test encounter error. How do I do that? For example, in one iteration, the data is completely constant and t.test gives error, the entire program terminates. I would like to write the information out to a file, and the loop should continue. Thanks My D. Coyne [[alternative HTML version

Hello, I would like to run a series of chisq.test() and store results (x-square, df, p-value) in a matrix for further analysis, but don't know how to do such.

So I have a select list with a list of items. When a user selects an item, another select list should have its default selected item set to a specific item (the default associated with the first select list). This is in a form to create a new task. The first select list is a list of parent tasks. When one selects the parent task, the clients select list must default to the same client as its

I have a log table which has a column recording the number of hours worked on a task. So there''ll be multiple lines for a particular task. I want to retrieve the total number of hours worked on a task, so that I can include the information when one views the task details. I can write a sql query to do this easily enough, like "SELECT SUM(hours) AS total FROM tasklog WHERE

Thanks for the advice. Going to look into this more this evening and hopefully get everything working. Thanks again!

Can''t seem to find an example of this anywhere - how do I populate a select list in a form from a database? I have a form to create a new task. The task is for a client, so there should be a select list populated from my clients table. I thought this would work: <%= select ''task'', ''client_id'', Client.find_all, "id", "name"

I'm ordering "The R Book" and hope to learn a lot more about R. In a meantime, I have a matrix of digits and I would like to look for a column that contains zeroes and remove the entire column from the matrix. I can write a piece of R code to do that (and it works); however, I think the R-experts have more tricks to do such a 'simple' thing. Many thanks in advance.
