I have a function that is called from a "sourced" script, whenever certain conditions are met. I have this inside it: if(P > 0.9)save( file = today() , myLMSmodel ); This gives me files that look like this: Thu Jan 8 14:04:43 2009 That works fine on my Mac, but it would be much more convenient to have something like this: LMSMOD_Jan_08_09_1404 Does anyone know how I can do

Thanks to everyone who helped me when I was totally clueless. Now I'm only partially clueless, and in writing functions, which is major progress. This is a function that is a major improvement over which I was using MS Excel for: function() { files <- list.files(pattern="ABN*") # All the models start with the letters ABN for( i in 1:length(files)) # loop through the

Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

Hello! I'm using Mac OS X 10.4.11 on a G4. I use the "R" command, straight from a terminal, because the "GUI" is slower, and I've never liked GUIs anyway. I tried to set up my environment to use the vi editor, but it always tries to save it in wierd things like this: "/private/tmp/RtmpWIhhuo/41a7" 13L, 161C written Sure I can "cp" it from that

Dear R-Community: I am assisting a community college instructor in an introductory statistics class. He has asked me to do this: Read in a file, of filenames, line by line: Student_models.txt : (contains 1500+ filenames) ________________________ Experiment_name_student_name_date_time_Model_number_etc_etc Another_file_name_with_similar_info_as_above And_another And_another_one

Hi: I have an array of measurements, that I've been doing linear regression model and AI models on. Because there are many errors and the values are "ill-formed" I would like to copy the array, but replace each value with the PERCENTILE of that value, in the original array. i.e. mesments$V1: 9, 77, -1 would become: mesmentsCopy$V1: 50, 100, 0 The actual array has many more

As part of my work, I am trying to append matrices onto data frames. Naively I assumed that when rbinding a data.frame and matrix, the matrix would be coerced and appended, keeping the names from the data frame. Clearly, I am not fully understanding the process by which rbind works. Example code: > A<-data.frame(1,1,1); names(A)=letters[1:3] ; B<-matrix(0,2,3) > rbind(A,B)

Peter, I am trying to get memdisk to work with grub and have run into a problem. Grub loads memdisk into the 0x9000 segment and then starts it at location 0x90200. I run into problems in the first printf statement. It turns out that printf uses a switch statement that compiles into a jump table. When I reach this jump table, I believe the code is jumping into hyperspace due to the jump table

Hey friends, I need a little assistance getting one of my applications running on OSX. I am able to install everything, and get my application running, but when I try to store an object in the session in one of my apps, the session object doesn''t get stored.

Please help, I have an application I switched over to UTF-8, but I am unable to decode URLs with unicode characters in them properly. For instance, if I have "item=Pur%E9ed" as a parameter in my url, when it''s decoded by rails, it returns "Pur?ed" and not "Pur?ed". Is there an easy way to fix my controller to accept these characters properly?

I'm written a function that uses nls in a loop to fit a model to resampled data. Occasionally a sample is drawn such that the algorithm (apparently) can't converge and step factor reduced below minimum is printed to the screen. I tried a few different settings for the minFactor parameter in nls.control with no different result. When this happens, I would like my function to put NAs

Does anyone out there have any thoughts on the type of load common DTrace scripts would cause on a system if run 24x7? I know "common DTrace scripts" and their underlining probe calls a vague statement. So for the lack of a common and establish set of scripts in the OS, I''ll use the most popular right for my question...the DTraceToolkit from Brendan Gregg. Which by the

Hi, What is the required size of the echo residue buffer in speex_echo_cancel function? The mdf.c source would suggest that it's frame_size + 1, while preprocessor.c source claims it's frame_size. Bug? Or am I missing something? I am using 1.2beta1. Thanks, Gregg

Hey guys, I wanted to share with you guys a detailed tutorial I just finished this weekend for using Acts_As_Ferret. http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial I started using Ferret and Acts_As_Ferret a few weeks ago, and I learned so much that I wanted to give back to the community by writing up a helpful tutorial that covers all the key topics in one

Please help, Does anyone know how to override the Mongrel request URI limits built in? I know it was set at a 512 byte limit, but my application will not work with this in place. Why do I need a larger limit? I''ve written a rails application that uses a bookmarklet to send large amounts of data from site to site. The only way to do this is (and keep it cross browser

Please help, I have followed the rails wiki to convert my rails application to use UTF-8: http://wiki.rubyonrails.com/rails/pages/HowToUseUnicodeStrings I am able to succesfully cut and paste Unicode characters from other page, successfully store and display unicode characters. However, my client actually wants ISO-8859-1 encoding, which I''m coming to realize is somehow

Hey Guys, This last week on the Rails Envy Podcast we received an "interesting" voicemail. Jason encouraged me to make a remix, and I think you guys will appreciate what resulted.

Good Morning, I have recently built R version 2.7.0 on a CentOS release 4.6, 64-bit system using the following command: ./configure --prefix=/usr/local/r-2.7.0 Everything built fine and works properly except for Rscript which is looking for files in the original build directory instead of the specified install directory. Did I forget to add a flag or is this a bug? TIA, Gregg.
