Hi Everyone, I am stuck with a simple problem. Suppose I have a vector x, and I want to calculate y[i]=3Dx[i+1]-x[i], it is very easy. I just need to write y<-x[2:length(x)]-x[1:length(x)-1]. Now if I know y, and want to know the vector x defined by x[i]=3Dx[i-1]+y[i-1] for all i, how can I do this without a loop? Thanks, Geoffrey PS. Sorry if you see a duplicate message. The previous

Hi all, When I write a script, I'd like to create a main() function so that I only need to type main() t re-run it. However, I'd like all the variables in main() to be global so that when the function terminates, I still have access to the variables in the environment. Does anyone know how to do that? Best regards, Geoffrey _______________________________________________________=0A=

Hi, I am really new at R. Does anyone know what is the real difference of vector and array, except that many operations that expect an array does not work on a vector?

Dear all, when using .jinit() I get the message .jinit() : Cannot create Java virtual machine (-1). The details: I am using the Dismo package.Dismo has a function 'maxent' that communi-cates with this program(MaxEnt).MaxEnt is available as a stand-alone Java program. It is normal when I execute the command : "jar <- paste(system.file(package="dismo"),

Dear all, I get the error when I use maxent.jar: Error .jcall(mxe, "S", "fit", c("autorun", "-e", afn, "-o", dirout, : java.lang.NoSuchMethodError: density.Params.readFromArgs([Ljava/lang/String;)Ljava/lang/String; sessionInfo() result: R version 2.14.0 (2011-10-31)Platform: i386-pc-mingw32/i386 (32-bit)locale:[1]

Campers -- In a few weeks there will be a bunch of people in Portland, OR, for a conference. A long time ago some campers mentioned that might be a good time for us to get together and hold a mini CampingConf for a few hours. Is anyone interested? Does anyone want to organize it? I''m thinking Wednesday night, May 16. We could possibly get a spot at FreeGeek (not likely since they are

I'm working on a Dovecot plugin, but I'm pretty new to Dovecot, so there's a LOT to learn about the code base and it's pretty slow going. I've got a few things coded so far, but I want to make sure I'm headed down the right path and get some advice before I go too much further. A couple years ago, I wrote some code for our Courier implementation that sent a magic UDP

Hi Everyone, I want to generate some random numbers according to some empirical distribution. Therefore I am looking for the inverse of an empirical cumulative distribution function. I haven't found any in R. Can anyone give a pointer? Thanks, Geoffrey _______________________________________________________=0A= =0A= =0A= The information in this email or in any file attached

hi Geoffrey, Since you are saying it happens on all types of volumes, lets do the following: 1) Create a dist-repl volume 2) Set the options etc you need. 3) enable gluster volume profile using "gluster volume profile <volname> start" 4) run the work load 5) give output of "gluster volume profile <volname> info" Repeat the steps above on new and old

False Positives I just discovered how easy it was to create a false positive when I, trying my first RSpec test, did this: ob.should eql?(''foo'') instead of: ob.should eql(''foo'') or: ob.should == ''foo'' As far as I can see, this is roughly equivalent to: ob.should false Neither eql?(''foo'') nor false causes the spec

Hi Was just using have_tag on an xml response and found the problem outlined and resolved here http://weblog.jamisbuck.org/2007/1/4/assert_xml_select Just wondered if there is any support in rspec?

Hi! I wonder does anybody planning to go beyond the default html formatter/report? The current html report is nice and green but what about to go a little silly and enable also user input. For example to let customer to add a new pending spec, comments etc. I feel it might be mentally easier for some customers to jump into spec world when it is possible to give input at "the same

Okay, I've traced it to a bug in configparser, which on my python 2.7.4 system is a backport of configparser from python 3. Here is a clean patch that works around the problem.

Hello, does anyone know how to take the mean for a subset of observations? For example, suppose my data looks like this: OBS NAME SCORE 1 Tom 92 2 Tom 88 3 Tom 56 4 James 85 5 James 75 6 James 32 7 Dawn 56 8 Dawn 91 9 Clara 95 10 Clara 84 Is there a way to get

Having used JUnit and Test::Unit, I''m quite used to having the ability to insert a failure message, which helps when tests fail. For instance, the example RSpec that is generated for a model class specifies that the model class is valid. Assuming this were supposed to be true, and it failed, I''ve now got to duplicate the code in the test in order to find out why it

I was planning on using a fixture within a description that didn''t modify the fixture, so I put it in a before(:all) block: describe "Customer", "xml" do fixtures :customers before(:all) do one = customers(:one) end # ... As a result, I got this message: 1) NoMethodError in ''Customer xml before(:all)'' You have a nil object when you

Dear all, I have a crash test cluster where i?ve tested the new version of GlusterFS (v3.7) before upgrading my HPC cluster in production. But? all my tests show me very very low performances. For my benches, as you can read below, I do some actions (untar, du, find, tar, rm) with linux kernel sources, dropping cache, each on distributed, replicated, distributed-replicated, single (single

I am working on a crude first-go-round-in-rails shopping cart and can''t figure out for the life of me the best way to do this. I have a shopping cart that has one page during the checkout that handles the address information, then the next handles the actual credit card information. How do I take the information from the address form and keep it alive long enough to put it in to

When I''ve got a view example like this: 1: response.should have_tag "fieldset#children" do 2: with_tag "child" 3: end If it can''t find ''child'', the error seems to come back as my_spec.rb:1 instead of my_spec.rb:2. Has anyone else experienced this? I just spent a while tracking down what I assumed was a problem in my have_tag only to
