driving R from Python (calldll?)
Sam Rushing's Python extension 'calldll' will supposedly give me access to any DLL, and presumably R.DLL in particular, from Python. I have no experience manipulating DLLs as yet. I am learning Python. I can't find any simple step-by-step instructions on how to get done what I want to do. Does anyone have experience with this? Is there a better way? Of course, one can use

are 588 sample frames subset or nonsubset?
Hi I am thinking of ripping albums to a single flac file with embedded cuesheet. As track and index points have to be on a 588 sample boundary due to the CD TOC standard working in 588 sample frames, I thought it may be beneficial to rip CDs with a blocksize of 588 samples. According to the format page on sourcefourge a stream is subset if "The blocksize bits in the frame header must be

UID syncing issues with CTDB
...e cluster to the domain without issues. I can also list my ad users and groups using wbinfo so I believe that my nsswitch.conf is set up properly. I am having problems with the UIDs and GIDs not matching between the two servers. For instance here is the output for getent on each server: Server A: jfarrar:*:20066:20001:Jeremy Farrar:/home/DOMAIN/jfarrar:/bin/bash Server B: jfarrar:*:20002:20001:Jeremy Farrar:/home/DOMAIN/jfarrar:/bin/bash The output looks good but the UID doesn't match. This will lead to some weird permissions issues in the future. THe strange thing is that it worked before. W...

are 588 sample frames subset or nonsubset?
...into the discrepancy but having the FLAC blocksize match the CD sample frame size is probably not desirable. the optimal blocksize for FLAC is relative to the stationarity of the signal and the 588 sample frame is not related to that, it's an artifact of optimal storage on CD.

monitor a simulation with a special console box?
I like to monitor simulation by reporting some current values to the console, every 25th iteration say. I think it might be nice to have that appear in a separate window. Anyone know how? regards, David Farrar New River Analytic [[alternative HTML version deleted]]

test of spatial dependence??
hello R-friends, I am a R beginner and try to ask a basic question: How to test the spatial dependence of a column of data? for example, I have 25 agricultural fields, and I measure the average slope (%) or pH for each field. All I have is 25 numbers. PS, could someone confirm that "spatial dependence" is equivalent to "spatial correlation" or "spatial

Bayesian data mining
Hi, I need a help to know whether I can perform the following in R: I have a set of observations (Ns) and each observation is drawn from a poisson distribution with an unkown mean, lambda. The set of lambdas in their turn are drawn from a common prior distribution which is supposed to be a a mixture of two gamma distributions. Is there a way to determine the poisson means in R, given the Ns and

Minimum valid number of observations for rpart
Hi, I wonder if anyone knows a study dealing with the minimum valid number of observations when using CART?. On top of that, when using RandomForest, is it possible to obtained a interpretable tree model as the graphical output of the analysis, just like in "rpart"? Thanks a lot in advance Javier Lozano Universidad de Le?n Spain

Equivalence of Mann-Whitney test and Kruskal-Wallis test with k=2
Hi all, The Kruskal-Wallis test is a generalization of the two-sample Mann-Whitney test to *k* samples. That being the case, the Kruskal-Wallis test with *k*=2 should give an identical p-value to the Mann-Whitney test, should it not? x1<-c(1:5) x2<-c(6,8,9,11) a<-wilcox.test(x1,x2,paired=FALSE) b<-kruskal.test(list(x1,x2),paired=FALSE) a$p.value [1] 0.01587302 b$p.value [1]
