Announcing... Planet R - a weblog aggregator for statistical computing Q: What is it? A: An aggregator for weblog posts about statistical computing topics, focused primarily around the R community. Q2: Where is it? A2: For now, at http://planetr.stderr.org Q3: What's it good for? A3: Hopefully, collecting resources and weblog posts from people who might otherwise not know about

Hi All, I'm getting some weird problems with merge(), which give me the Error in match.names(clabs, names(xi)) : names do not match previous names Error. I've found other people discussing this error, but they don't seem to match my situation, and the strange thing is that changing the order of the data frames that I'm merging can remove the error. For example: bt <-

Dear Srinidhi, You are trying to fit 1 random intercept and 2 random slopes per individual, while you have at most 3 observations per individual. You simply don't have enough data to fit the random slopes. Reduce the random part to (1|ID). Best regards, Thierry ir.

I am running a multilevel growth curve model to examine predictors of social anhedonia (SA) trajectory through ages 12, 15 and 18. SA is a continuous numeric variable. The age variable (Index1) has been coded as 0 for age 12, 1 for age 15 and 2 for age 18. I am currently using a time varying predictor, stress (LSI), which was measured at ages 12, 15 and 18, to examine whether trajectory/variation

Hi, When adding an index to another one using add_indexes I get duplicates even though I use the :key attribute. For example: def test_add_indexes_uniqueness index1 = Ferret::Index::Index.new(:key => :id) index2 = Ferret::Index::Index.new(:key => :id) # Add two items with same id index1 << {:id => 23, :data => "This is the data..."}

Hi, I have a datetime select in my form like this: DATE/TIME REPORTED: <%= datetime_select ''report'', ''rep_date'' %> This works beautifully for creating a new record. The data is saved as: 2006-08-07 11:33:00 Now, the problem is when I try to load the form with saved values to do an update. The above code works and loads the saved data in another one

Dear List, Let's say I have a list whose components are 2 matrices (as exemplified in the "mylist" object below). I'd like to create a list with components being 4 matrices based on an logical index vector. is there a way to simplify what I'm doing to obtain the results in "mylist2"? I'd like something that would work on an arbitrary number of elements in

When I try to run the following non-linear regression with variables index1 and prl3: > beta = 4 > nls(index1~beta*(1/prl3),start = list(beta = 4)) I get this error message: Error in nls(index1 ~ beta * (1/prl3), start = list(beta = 4)) : REAL() can only be applied to a 'numeric', not a 'logical' I've got no clue as to the REAL() to which this is referring. Any

Hi, I am trying to run a linear mixed effect model on data. I have 17 longitudinal subjects and 36 single subjects, and this is the code I'm using (below). So, INDEX1 is the column with brain volumns, and the predictors are gort and age, by time ID (time they were seen). I believe my data is set up the right way, but when I run it, I get DF for Intercept is 49, and DF for slope is 13?

Hey, We hit a bug today because Arel::Visitors::ToSql is not threadsafe. Here is what is happening: Arel::Visitors::ENGINE_VISITORS is a cache of visitors instances. These instances are not inherently threadsafe because it contains state ''@last_column'', ''@connection'' that is shared between threads. The other variables ''@pool'',

Hi, I am a Ph.D. student from Québec, Canada. I’m a beginner with R and Bioconductor. Until now the only experience I have is in analyzing microarray data using affy and limma packages. Now I am trying to analyze Rat Gene 10 st arrays and I would like to run RMA analysis and Smyth moderated t test on those arrays. Since no cdf official package is available for those arrays, after reading many

Hello everybody, I have a question about lazy_expunge plugin. I set up Dovecot with lazy_expunge plugin on a Debian Wheezy machine; I setup also a global acl to keep .expunged namespace readonly for all users. Imap client is Horde Webmail Edition 5.2.3 When I try to delete folders containing subfolders, lazy_expunge copies into expunged private namespace only the upper level folder. The subfolder
