Is there any way to put an argument into an object name. For example, say I have 5 objects, model1, model2, model3, model4 and model5. I would like to make a vector of the r.squares from each model by code such as this: rsq <- summary(model1)$r.squared for(i in 2:5){ rsq <- c(rsq, summary(model%i%)$r.squared) } So I assign the first value to rsq then cycle through models 2 through

Dear R wizes, I have a data.frame of species abundances with column names consisting of 4 letter codes then an underscore and a number like this: abco_1, abco_2, abco_3, psm_1, psme_2, psme_3, etc. I would like to get an identifier for all the abco, and psme and other species etc. I used spec.fact<-substring(names(spec.count),1,4) To make a vector of the first 4 letters of

Hi R folks, I'd like to announce several new R users groups here in SF, LA, NYC, and Ottawa - as well as their next scheduled event. The goal of these user groups, besides gently explaining 'drop=TRUE' to the uninitiated, is to exchange knowledge, promote best practices, and spur the adoption of R for innovative applications. If I've missed any groups here, please feel to add on

Hello everyone. In matlab  (again) there is a fucntion find that returns you the indexes where the condition in find was met. I want the same functionality in R i.e find(Mydata>2) to return all the indexes where the condition is met. Do you know something like that? Also when I try to search in google using for example the word R inside the search lemma I get very few results as the R confuses

Hello everyone, I did some initial tests and it seems that mongrel does not support byte-range requests. Is this correct? The reason I ask is that the iPhone requires byte-range requests to work in order to stream audio or video from a web server. Thanks in advance, alan

Hi, I''ve configured mongrel_clusters behind an Apache 2.2 proxy using named virtual host. Session are saved as ActiveRecordSession. But the cookies created on client side doesn''t correspond to session data saved in database (keys are different). The RoR app react just like it doesn''t have a session at all. If I don''t use Apache as a proxy/load balancer

My apologies to all who downloaded preview6, it did not contain Rails 1.0 as advertised -- I screwed up! Preview7 does, in fact, contain Rails 1.0 and as a bonus, also includes Typo 2.6.0 as a preinstalled sample app. See the Getting Started page for instructions on running Typo in Instant Rails: http://instantrails.rubyforge.org/wiki/wiki.pl?Getting_Started Also, you can thank David Morton

This release upgrades the included Ruby to version 1.8.4 and will become the final 1.0 release of Instant Rails if no serious problems are found.

No installer, you simply drop it into the directory of your choice and run it. It does not modify your system environment.

We just upgraded from 2.1.16 to 2.2.13. One user is experiencing problems when using the shared namespace. Specifically it happens when opening/reading a message and when deleting messages. These functions work for other users. So far, this appears to be only affecting one user. The shared folder is a local ext4 file system and utilizes acls # 2.2.13:

Hi all - I am far from fluent in R and need some help polishing up a figure I am trying to create. I wish to make a "tileplot" (from package extraLattice) where the x axis is time (months; may - sept) and the y axis is space (fishery management zones). Here is my code so far: tileplot(effort~month_num*-area_num,mae,col.regions=topo.colors(100), border =

Dear R users, I would like to fit a glm with Poisson distribution and log link with a known dispersion parameter. I do not want to estimate the dispersion parameter. I know what it is, so I simply want to fix it at a constant for this and other models to follow. My simple, no covariate model is: Tall.glm<-glm(Seedling~1, family=poisson, offset(log(area)), data=tallPSME.df) I want to

We're currently running 2.1.16. I've been wanting to update to a 2.2.X version, but have been running into problems, even with the latest (2.2.12). I'm not sure at what version this issue appeared, but I believe I've tried 2.2.10, 2.2.11, and now 2.2.12. We have a shared maildir setup. With that configuration in place and with a user in the dovecot-acl file, I can do the
