similar to: large data set, and RDBMS

Hi I've experienced some unpleasant behaviour while attempting to connect to an Empress 8.6.2 RDBMS via RODBC 1.2-3 and a freshly minted R 2.6.2.pat on a SLED linux system where a call to odbcConnect() to initiate the odbc connection causes R 2.6.2.pat to segfault. The odbcConnect call is CHANNEL <- odbcConnect("myEmpressDB", uid="myusername",

This may seem off the wall, but can dovecot be configured to support a connection to a database server and use the database server to store the e-mail message and its attachments? While you can use Postgres and MySQL for storing and authenticating users, there is a possibility to use an RDBMs to control the mail itself. Thoughts? -- Michael Segel Principal MSCC

I want to be able to exctract a matrix from a data frame that contains repeated measurements for individuals. i.e I want to exctract the second observation for each individual in the study. Is there a way of doing this? I guess what I am trying to ask is if there as a multidimensional version of aggregate() as in aggregate(data, list(data[,"ID"]), function(x) x[2,]) but aggregate will

Hello, When I try to run "rake clone_structure_to_test" on my project, I get the following errors: $ rake clone_structure_to_test (in /home/www/cedscreening) psql:db/development_structure.sql:8: ERROR: permission denied to set session authorization psql:db/development_structure.sql:16: ERROR: permission denied for schema public psql:db/development_structure.sql:34: NOTICE: CREATE

I'm not sure if this is the best subject line, and I apologize in advanced for the cross-posting, but I've been trying to get past a piece of code for two days now, and seem to have narrowed where a show stopping crash is occurring... I keep getting: psql:../sql/schedpak.sql:257: server closed the connection unexpectedly This probably means the server terminated abnormally before or

ok, so I removed the default postgresql install and installed it from the software collections.. following the instructions at https://www.softwarecollections.org/en/scls/rhscl/rh-postgresql95/ and I get this [root at home1p /home/jason]$scl enable rh-postgresql95 bash [root at HOME1P jason]# postgresql-setup --initdb * Initializing database in

Dear list, I try to update the prabclus package. R CMD check works nicely, no warnings, good results in all tests. However, building the package fails: ginkgo:/disk5/home/chrish/RAusw/libsrc R CMD build prabclus * checking for file 'prabclus/DESCRIPTION' ...

Hi A while back I used gsub to do the following temp<-"000US00231" gsub("something here", "", temp) "00231" I think it involved the `meta characters' somehow. I do not know how to do this anymore. I know strsplit will also work but I remember gsub was much faster. In essence the question is how to delete all characters before a particular

Dear all, I am interested in finding out how to change the names of coefficients in the lm function. I have a design matrix which I called "design" where each variate has its own name. However when I issue the command: lm.1<-lm(response~design-1, weights=some.weights) and follow it with: summary(lm.1) it seems to paste as a character the names of the variates with design i.e I

FIXME this patch isn't complete, still need to figure out the ldap command to wait for that service, something along the lines of: ldapsearch -b dc=priv,dc=ovirt,dc=org -x (but how will we parse the base from the installer? also this cmd fails, how to fix?) --- installer/modules/ovirt/manifests/ovirt.pp | 8 +++++- installer/modules/ovirt/manifests/postgres.pp | 13 ++++++---

Hi, I'm trying to install Areskicc but with no much sucess. After installing the UI I login as root/mypass, but in the left menu I only have 3 options: Main Template, disconnect and logout. When I click on Mail Template> Show mail template it shows an error page. First, is there a way to increase the debugging level so I can know what's going on behind the scenes? Second, I've

I have this awkward problem with trellis (lattice). I am trying to generate some plots through loops but the .eps file is empty. When I generate them in a list and print them outside the loop all is fine. this is an example below:( nothing shows up in foo.eps, but all show up in foo1.eps) R vesion 2.0.1, lattice version 0.10-16, on a debian 2.6.8-1 kernel. X <- data.frame(x=rnorm(10000),

Hello I have a problem that has exhausted my ingenuity and would like pointers to a solution, or at least where to debug. - I am using R and postgresql. - I have databases on two different servers. - I have a few users, who use different client machines - whose R installations are identical (rsync'd) >From one client machine I can access databases on both servers, using both psql and by

I''m at a loss to explain why the postgres gem will not work on my new server. I''ve gotten it working on several other servers in the past. The major difference between then and now is that I''m using a newer version of PostgreSQL. 8.x as opposed to 7.x. === Server setup OS: Fedora Core 6 (Commands shown with "$" are performed as the same user that mongrel

Hi, Is there a function that does percentile-percentile plot. I do not mean the qqplot. I need to plot the percentiles rather than points themselves. I am hoping for a plot that tells me that the x percentile of one data set corresponds to the y percentile of the other. for example a point on the plot of (.5, .2) will tell me that the 50th percentile of the first data and the 20th percentile of

Hi There I have a lm object with 4 parameters and I want to test wether 2 parameters are equal using a Wald test (basically b1=b2 or b1-b2 =0). In the help file from R it says that under ANOVA the optional arguments " Terms" or "L" test whether a linear combination is equal to 0. I tried; >anova(m1, Terms = Beta1-Beta2=0) but I get the error: Object " Beta1"
