Dear R Users, I am working with gsub for the first time. I am trying to remove some characters from a string. I have hit the problem where the period is the shorthand for 'everything' in the R language when what I want to remove is the actual periods. In the example below, I simply want to remove the periods as I have removed the comma, but instead the complete string is wiped out. I

Dear All,   I have the following code set up:   x <-2000 y <-8 z <-3   I would need to use these numbers to show up in my plot title "mixed" with text.

Hi all... I?m making a chart dealing with frequencies of isotopes of various elements. For instance, I'd like the following text to appear on a chart with the "35" and "37" as superscripts: Based upon: 35Cl: 75% 37Cl: 25% I am having problems properly parsing the superscript that preceeds the "Cl", since there is no character ahead of the superscript (I saw

I tried the mime thing but it did not help. I didn''t think it was that because I can get the mp3 served OK hitting the URL in a browser. I just noticed that I am getting an error in Mongrel when WinAmp make the request for the mp3 file: BAD CLIENT (127.0.0.1): Invalid HTTP format, parsing fails.

Hi, I am reading a large space-delimited text file into R (41 columns and many rows) and need to do run each row's values through another R object and then write to another text file. So, far using readLines and writeLines seems to be the best bet. I've gotten the data exchange working except each row is read in as one 'chunk', meaning the row has all values between two quotes

I''m using monit to restart mongrel processes if they go away. With mongrel 0.3 I could issue a start command and the process would start up even if the .pid file existed (though a warning would appear). Now, with mongrel 1.0.1 the warning says I must clear the .pid file and the process is not started. Is there anyway to force it to start without having to clear the .pid? Regards

Mongrel 0.3.13.3 Windows XP Rails 1.1.6 I have a rails app that serves up mp3 files via the send_file command. We create a playlist (M3U) with URLs to the mp3s.

After playing around I found that if I am running Rails under Webrick WinAmp

I have Mongrel Cluster setup with Apache a mod_proxy_balancer. I''ve seen (from time to time) mongrel instances become non-responsive. Is there anyway to configure the balancer so that it "knows" which processes are no longer good and stops trying to use them? _______________________________________________________ The FREE service that prevents junk email

Hi everybody, I would like to delete rows based on duplicate entries in column 3 in the data matrix X (size 60000 x 57). I have tried the unique(x) command as > data <- X[unique(X[,3]),] however, for some reason the command introduces a lot of NA's into the dataset. So, now I'm looking for a function that eliminates rows, if they have duplicate values in column 3. Does anyone
