Hi there. I needed to recompile xapi to fix a bug that was resolved regarding vdi-create not setting the sharable flag. I used the sources provided in the source-1.iso from xen.org. Everything is good in this regard, and creating a vdi that has "sharable=true" is possible, but I had a problem that forced me to revert to the older copy of the xapi binary because my XCP box was now being

This is probably something very simple but I can''t seem to figure out why I keep getting the ''wrong number of arguments (1 for 2)'' error with the following code when I try to create a new record.

Is anyone else encountering trouble viewing the basic www.r-project.org page? Or has it been changed recently so that google hasn't kept up? I find I can access the mirror of the CRAN page at http://www.maths.bris.ac.uk/R/, none of the *.org pages. Nor can I jump to the R homepage from the CRAN mirror. JWDougherty

Hello, I have a problem with selecting the right type of sums of squares for an ANCOVA for my specific experimental data and hypotheses. I do have a basic understanding of the differences between Type-I, II, and III SSs, have read about the principle of marginality, and read Venable's "Exegeses on Linear Models" (http://www.stats.ox.ac.uk/pub/MASS3/Exegeses.pdf).

I am trying to import a SPSS.sav file into R. The attached file is not technically the file I am trying to import, but does replicate my problem. The actual file is much too large to attach. No matter what I do, I can not get R (base or Hmisc) to apply the value labels in the .sav file to the dataframe created in R. Here's the code that I am using. maine <- spss.get("test.sav") #

I'm trying to obtain within-group correlations on a subset of variables. I first selected my variables using the following command: mydata$x<-mydata[c("iq","education","achievement")] I'd like to look at correlations among those variables separately for men and women. My gender variable in mydata is coded 1 (women) and 0 (men). I have successfully used

I have a generally successful compiled R 1.8.0 version installed on a SuSE 9.0 system. One frustration however is that the basic keyboard functions of BASH have not completely carried through and the up, down, left and right arrow keys don't behave as they do on the regular shell command line. That is no command history can be accessed and the cursor cannot be back-spaced over a

I've been playing around with various table tools, trying to construct a fairly simple cross-tab. It shouldn't be hard, but for some reason it turning out to be (for me). If I want to see how many men and how many women agree with a agree/disagree question (coded 1,0), I can do this: >attach(mydata) >mytable <- table(male, q1.bin) # gender and a binary response variable

Hi All, I am attempting to simulation an inventory model on R and I am having some problems. I believe the problem is when I define my demand rate is stays constant throughout so when I do need to reorder the model does not recognise it as I have the initial supply arrival time set to infinity at the start as no order has been played but I have an if statement saying, if the level falls below a

Hi Gurus- I want to return the variety from the species table based on the active record link to inventory table class Species < ActiveRecord::Base has_many :inventories end class Inventory < ActiveRecord::Base belongs_to :species (this is the singular and the plural, so that''s OK) end My inventory_controller looks like: def show @inventory =

Hello, I''m developing an app that basically, receives a 10MB or less XLSX files with +30000 rows or so, and another XLSX file with about 200rows, I have to read one row of the smallest file, look it up on the largest file and write data from both files to a new one. I just did a test reading a few rows from the largest file using ROO (Spreadsheet doesn''t support XSLX and

I have a puppet master install which uses puppetdb. I also have puppet dashboard installed with the inventory service running. I want multiple puppet masters using a single puppetDB server. Puppetdb is installed on separate vm. How can I get the dashboard inventory to use the puppetdb server to get the inventory records? Where do I configure the dashboard inventory so it uses puppetdb?

Railers: Greetings from the low end of the learning curve. I have installed all the prerequisites on Win32, including a lite MySQL database with a table in it called Inventory. Then I run this command line... ruby script/generate ajax_scaffold Inventory ...and I get this error message: error Before updating scaffolding from new DB schema, try creating a table for your model

I just set up the latest dashboard release candidate in hopes of trying out the new inventory service. After modifying the puppet- dashboard config to use the inventory service and after changing my auth.conf I gave it a whirl but ran into some issues.. I initially tried using fact_terminus = yaml and was able to do some queries via curl. I''m currently using storeconfigs so setting up

Hi All, Puppet-dashboard appears to be having some trouble. Under inventory, it says: "Could not retrieve facts from inventory service: Permission denied - certs/dashboard.private_key.pem" When I run: curl -k -H "Accept: yaml" https://puppet:8140/production/facts/host.domain I get the expected dump of facts.

Hi all, We have a mixed Linux and Windows environment and have so far just been using Puppet on our Linux servers. Having configured the inventory service, we''ve got an auditing script that uses the data to report on things like OS version, RAM, etc. This is all so nice that we''d like to extend it to auditing our Windows infrastructure. However, at this point in time, we have
