function optimization: reducing the computing time
Dear useRs, I have written a function that implements a Bayesian method to compare a patient's score on two tasks with that of a small control group, as described in Crawford, J. and Garthwaite, P. (2007). Comparison of a single case to a control or normative sample in neuropsychology: Development of a bayesian approach. Cognitive Neuropsychology, 24(4):343?372. The function (see below) return the expected results, but the time needed to compute is quite long (at least for a test that may be routinely used). There is certainly room for improvement. It would really be h...

Error message when calling t.test() and aov() with a factor variables
...for factors Not a big deal and trying to catch all of the silly things users may do is of course impossible, but for this one adding a check that the (response) variable is actually numeric could be useful.

A concrete type I/III Sum of square problem
...SS and, if so how to enter my design in Anova (car package, I still have not the J. Fox's book) ?

Natural vs National in R signon banner?
The R signon banner includes this statement: Natural language support but running in an English locale Should that not say 'National' instead of 'Natural'? Meaning that LOCALE support is enabled, not that the interface understands human language? Please ignore this and forgive me if this is an inappropriate post. I am a N00B in R.

System of related regression equations
Dear all, I would like to estimate a system of regression equations of the following form: y1 = a1 + b1 x1 + b2x2 + e1 y2 = a2 + c1 y1 + c2 x2 + c3 x3 + e2 Specifically the dependent variable in Equation 1 appears as an independent variable in Equation 2. Additionally some independent variables that appear in Equation 1 are also included in Equation 2. I assume that I cannot estimate these two

Extract confidence intervals from rma object (metafor package)
Dear R-experts! I am working on some meta-analysis using the metafor package. I would like to extract values of the confidence intervals of the effect sizes of the single studies from an rma object. Those values are printed out when plotting a forest plot using the forest function on the rma object, however I was not able to locate them. Many thanks for your help! Jokel [[alternative HTML

metafor: including phylogenetic non-independence among species?
Hello, Is it possible to include information about phylogenetic relatedness among species (when species are replicates for each study within a meta-analysis) in a meta-anlaysis in the metafor package? Alternatively, I wonder if the method f Lajeunesse 2009 American Naturalist has been adopted in R in any fashion? Thanks, Scott Chamberlain [[alternative HTML version deleted]]
