Dear R-help-list, I started using R coming from the former use of SPSS, mainly writing my own syntax. I do classical experimental cognitive psychology and am interested in the cognitive control of task sequences (i.e. classification task). Especially I am interested in the performance of the actual depending on the tasks before. Thus, in SPSS I create variables like this one: Compute cond = 0. If (task_2=task) cond=1 else cond=2....

Hi - attached is a patch to enable building DragonEgg (x86_64) for LLVM3.3 and LLVM3.4. That is, add these changes to the 3.3 release, and it becomes possible to build DragonEgg against a llvm3.4 compiler.

I really like the built-in Mac OS editor for R, so I hope this will be fixed soon or I can easily fix it myself. Thanks, Sascha W. --- Sascha A.

...on 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 helpful if some experts of you may have a look...

I want to predict values from an existing lm (linear model, e.g. lm.obj) result in R using a new set of predictor variables (e.g. newdata). However, it seems that because my linear models was made by calling scale() on the target predictor that predict exits with an error, "Error in scale(xxA, center = 9.7846094491829, scale = 0.959413568556403) : object 'xxA' not found".

...all the reference-counting machinery is a complete waste of time and code and RAM and the program would run strictly faster if it was ripped out. I don't know for sure (it's a lot more work to try!), but I would not be surprised to see a further 10%-20% speedup. And then you come to the cognitive load on the programmer, trying to decide whether to use IntrusiveRefCntPtr or shared_ptr or unique_ptr or auto_ptr or weak_ptr or whether and where to call free()/delete. And the extra typing needed to write it instead of using a raw pointer. And the extra time and cognitive load to read the code....

...aire. http://shared.openheartlogic.org My collaborator (equally stats inept) is working on a similar web-based questionaire http://ruminate.openheartlogic.org Ultimately, we want to publish in a peer-reviewed journal such as Emotion & Cognition or, at least, get a paper accepted at the annual Cognitive Science conference. Something like that. We have already started collecting data but not on a large scale since we are not confident about our statistical approach. This is a shot in the dark, but if a stats expert wants to collaborate with us then we would welcome that. We don't have much t...

Hi All: Just wanted to wind this up and summarize the results. Although there were a few no votes, it looks like there's a consensus for adding a `isa_and_nonnull` type operator. While there were some who preferred `isa_nonnull`, it wasn't overwhelming, and since `isa_and_nonnull` is already committed, I'm going to leave it as `isa_and_nonnull` for the time being. Thanks for all

Hello, I apologize that this is off-topic. I am seeking information on perception of graphical data, in an effort to improve the plots I produce. Would anyone point me to literature reviews in this area? (Or keywords to try on google?) Is this located somewhere near cognitive science, psychology, human factors research? For example, some specific questions I have are: I recall as a child when I first saw a map where the areas of the containers (geographical states) were drawn as rectangles, proportional to a quantity other than land area. Does anyone know of an algor...

Hi, I have a question that I have not been succesful in finding a definitive answer to; and I was hoping someone here could give me some pointers to the right place in the literature. A. We have 4 sets of data, A(t), B(t), C(t), and D(t). Each of these consists of a series of counts obtained in sequential time-intervals: so for example, A(t) would be something like: Count A(t): 25,

R for OS X, version 2.0.1 Has the add parameter of plot commands been deprecated? It no longer occurs in the help listing for plot, and doesn't work, either.
