Hello, I''m trying to run rails on a Solaris 10 box with Ruby/OCI8, but I''m getting the following errors when trying to start up. # script/server => Booting WEBrick... /usr/local/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/commands/servers/ webrick.rb:49:in `[]='': failed to allocate memory (NoMemoryError) from /usr/local/lib/ruby/gems/1.8/gems/rails-1.1.2/lib/

Howdy folks, Has anyone had any luck getting Oracle''s XMLType to play nicely with Rails? According to the docs, it''s just a wrapper around CLOB. However the ruby-oci8 driver throws an exception about user defined types if you try to query a table with an XMLType column. Any pointers would be appreciated. Thanks, -wilig

All of a sudden, on three different systems, the "server_ip_address/sid_name" syntax in database.yml has stopped working for me. I can''t even do a OCI8.new(blah blah blah) statement from an IRB shell. I get "ORA-12541: TNS:no listener", or some variant, depending on how I phrase it. On systems where I have a real deal client installed, and OCI can find the tnsnames

I would like to install the package "growth" as it contains the function "corgram" and some other presumably useful stuff for time series analysis.

Hello, I have Oracle XE installed. I have a table USERS. When I try to generate a scaffold it gives me this error. I tried also with Mysql and it worked.

I am using this code to calculate the moving average mean.It worked fine but when I wanted to also calculate based on sd(stander deviation) I got the error shown below. I read this documentation of R movingFun and found that sd was mentioned at http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/raster/html/movingFun.html I wonder if needs any other things to conseder or sd is not at all supplied by this function. sami<- list.files("C:\\Usersfinal-2010", "*.envi", full.names = TRUE) saf=stack(sami) dm <- overlay(saf ,fun=func...

...screen is not large enough), and thus to accommodate with very high rows and tiny columns. This flaw led several useRs to develop alternative functions in external packages : http://bioinformatics.mdanderson.org/Software/OOMPA/ClassDiscovery/html/aspectHeatmap.html http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/gplots/html/heatmap.2.html But after a quick look at the "stats" package sources, this seems quite easy to fix, without breaking backward compatibility : [ src/library/stats/R/dendrogram.R ] - line 689 : add "width=1" and "height=1" as arguments to hea...

I am new to RoR, but totally sold to the concepts, so I have decided to use RoR to develop a web client to our Oracle-based software that our customers today use with a Windows client. At first we will develope simple things like registering to receive email newsletters, and registering/updating your name, address and telephone etc. Eventually we hope to do a more full-bodied web-side client.

Is rails + oci8 + mac os x intel a winning combination? It appears that oci8 might be a issue.

Hi Can anyone tell me how to convert an image file (a jpg file for instance) into a matrix file? The command image(blabla) transforms a matrix into an image file, I am searching exactly the inverse. Thanks... [[alternative HTML version deleted]]

Dear researchers I wish to plot a box plot without the mean line (the black line) and the i wish a full line for the standard deviation This is an example mytest <- c(2.1,2.6,2.7,3.2,4.1,4.3,5.2,5.1,4.8,1.8,1.4,2.5,2.7,3.1,2.6,2.8) boxplot(mytest) really thanks Gianni [[alternative HTML version deleted]]

...wo (actually 3) groups. Disclaimer: I am quite new to R, so I might be missing some terminology that I have not come across.   I am trying to find out if I can easily implement a Wald test in R for this, but the only relevant thing that I came across is this link (http://hosho.ees.hokudai.ac.jp/~kubo/Rdoc/library/aod/html/wald.test.html), which seems to be referring to comparing the coefficients of separate IVs within the same regression. What I am interested is to compare the coefficients of the same IVs across three regressions and across three groups.  Some basic information about my mod...

Dear editor: I'm writing this letter to enquire where can I download the package of "lmtest". Can you send me this package? THanks a lot. Best regards, Shu-Fei Wu

Hello all. I am using the Paginate_with_ajax code as described on the wiki but I am running into the following problem. The following code will work fine and retrieved unsorted records in a hunky dory fashion: @componentlogs = Componentlog.find(:all, :conditions => [ "cl_compname like ?", @criteria ], :offset => offset, :limit => items_per_page ) However if I try and add an
