...formats (lotus, etc). Does exist any way to do it within R? The main problem is that many spreadsheet data use comma as decimal separator and not the point as needed in R (and many software for Linux), so importing data first as a tab separated values does not solve this problem.

...ut aggregating several IMAP sources and a IMAP aggregator proxy would come very handy. I just read: http://www.cyrusimap.org/mediawiki/index.php/Cyrus_Murder_Design and found it very interesting. Anyone did something similar based on: http://tools.ietf.org/html/rfc3656 Thanx. Erny -- Ernesto Revilla Yaco Sistemas +34 954 500 057

Hello, I want to arrange data from a table to perform a simple regression. All the examples I saw deal with paired data, e.g. 'x' and 'y' have the same dimensions (e.g. 5 values for x and 5 for y). But I have more than one 'y' for each 'x' value, e.g. the data file has a x = 0, 30, 60, and 120 columns. And for each of them I have several replicate responses (e.g.

Hi all, I recently proposed a change in R that has led to the addition of new code to the R source code. The code added, as far as I know, has no tests and it might affect many packages in CRAN. I was wondering if adding a test would be helpful or it is already covered by some other test. Which brought me to the question: what is the coverage of R checks (check-devel)? My searches in the

Hi. Does anyone know of a good imap stress testing tool? And one which supports SEARCH commands? I have to compare Courier and Dovecot. I already did some tests using a modified postal/rabid package. I would be thankfully for any hints. Best regards. Erny Yaco Sistemas Spain

Hi! Thanks for this service! It is very helpful to know what is being developed. I distribute the content to other venues and I noticed some times that the updates are duplicated. For example, the sentence "?is.R()? is deprecated as no other S dialect is known to be in use (and this could only identify historical dialects, not future ones)." is duplicated in different days: Day 1:

Dear all, I am fitting a nonlinear mixed-effects model from a balanced panel of data using nlme. I would like to know whay would be the best options for formally testing for autocorrelation. Is it possible to carry out a Durbin-Watson test on a nlme object? As far as I've seen, I think the durbin.watson function from the car package just works on lm objects. Thank you very much, Antonio

Hi. I'm using dovecot 2.0.9. Is there already a way to remove unused IMAP keywords from a folder? I searched in google, wiki, etc. but didn't find anything useful. Thanx. Regards Erny

Dear all, I am trying to fit a nonlinear model with a autocorrelation term, but everytime I type in the command, I got an error message from Winwows and R closes itself. The command line is as follows: mod1<-nlme(V~A*exp(-B*A.O)*Vac.t.1.,data,fixed=A+B~1,random=A+B~1|ORDINAL,+ correlation=corCAR1(0.3179,~A.O|ORDINAL,TRUE),start=c(A=1.2,B=0.2)) I have already fitted this model allowing Phi to

Dear all, I am trying to fit a mixed-effects non linear regression, but I have some trouble with it. My data are a balanced panel of 904 subjects with 8 observations (at regular periods) per subject. The functional form of my model is Y=Aexp(-BX1)X2 +e. I want to allow parameters A and B to vary among subjects and also include an autocorrelation term. I have already fitted a standard nonlinear

Dear list members, I am facing a 3-level model, for which my research hypotheses suggest that the variance of both level-1 and level-2 residuals may be a function of a level-3 variable. To be a bit more clear: I am fitting a longitudinal model for a panel of companies grouped in industries. I suggest that some industry variables may create 'unexpected' shocks at especific points in

Dear list members, I am working with a multilevel growth curve, that in its simplest form goes like follows: Yit = Ai + Bi t + eit (the error term is assumed to follow an AR(1) autorregressive process) One major topic in my research is the convergence in the values of Y over time. Thus, I am interested in the relationship between the random effects for the intercept and the slope, and I

Dear all. (I'm new to the list.) Our regional government is considering, due to our proposal, migrate from Courier to Dovecot. 70k mailboxes. One of the most attractive features for them is the usage of indexes, and especially Solr FTS plugin. Their question is: How many users (range of users) could support one Solr instance used as index and search backend? Are there any deployment
