Dear R-users, Sorry for bothering you twice in a day, but I was wondering whether there is any R-function which can easily plot the single elements of a Lexis diagram. I though that Lexis.diagram(Epi) could be the case, but it just plot life times in a frame. In particular I have been searching for something similar to the function "image" which can plot either the single triangles of a Lexis diagram or the parallelograms (e.g. probability of...

...survSplit() to work, but it appears to have a problem with end times on the boundaries of the intervals. (My intervals are [0,183], [184,365], [366,548], [549,730], [730,Inf]). I looked in the searchable archives and found that others had also discovered problems with survSplit() and suggested Lexis() in the Epi package. When I try to get Lexis to work, I get an error message that I cannot interpret: > addictscdf<-Lexis(entry=start,exit=stop,fail='status',breaks=c(184,366,549,730), + include=c('id','clinic','prison','meth','clinic01'...

...ed the plot function in the base package   > plot(X, Y)   This gave me a graph which might be mistaken to be starting from the origin, and yet, using the same numbers in Excel, and plotting them using the scatter option, I get a graph which clearly has a positive y-axis intercept. Please help.   Lexi [[alternative HTML version deleted]]

...interested in the provenance of the name "normal distribution" (for what I'd really prefer to call the "Gaussian" distribution). According to Wikipedia, "The name "normal distribution" was coined independently by Charles S. Peirce, Francis Galton and Wilhelm Lexis around 1875." So be it, if that was the case -- but I would like to know why they chose the name "normal": what did they intend to convey? As background: I'm reflecting a bit on the usage in statistics of "everyday language" as techincal terms, as in "significan...

...')' in "Dcr[[5]][1:29]+Dcr$Dbobc3[1:29])" NB: In the equation with error message, only the last term is specified by referencing its name (ie., Dcr$Dbobc3[1:29]. Also note that the error occurs whether I append '[1:29]' to Dcr$Dbobc or not. How do I resolve this? Thanks.

...39;d offer these to the general community. These were all built against up-to-date patched boxes for the respective RedHat releases. These all appear to work on my various boxes, but feedback would be appreciated if you run into a dependency problem. You can get them all from http://bamboo.lexi.com/openssh or anonymous FTP at bamboo.lexi.com/pub/openssh/rpm . If anyone from the development team is interested, I'd be willing to make RPMs for older platforms to go on the main FTP site. I'm not sure what sorts of security procedures are in place with the team to make sure these...

To the R developers, The discussion below reminded me that I think it might be a good idea to take the Relevel function from the Lexis package and replace relevel in stats with it. This is really nothing special for epidemiology. It is fully compatible with the existing relevel (it actually contains the relevel code almost verbatim as a subset), but it has the extra functionality of combining levels. I put the .R and .Rd files...

hi all, after fitting a multiple linear regression model <- lm(y ~ a + b+ c+d) i wanted to plot diagnostics plot(model) but get the error message Error in object$coefficients : $ operator is invalid for atomic vectors. which does not make a lot of sense, since there is no "$" - i am working with an attached dataset. can anyone help, please?? thanks a lot, kat

Hola, Sí, lo puedes hacer de esta forma... #----------------- set.seed(20) DATOS <- data.frame ( ID = c (1:10) , TIEMPO = sample(1:40, 10, replace=F) , DEF = as.factor(sample(c(0,1), 10, replace=T)) ) library(ggplot2) ggplot( data = DATOS ) + geom_point( aes(x = TIEMPO, y = ID , shape = DEF, color = DEF), size = 5 ) + geom_segment( aes( x = 0, y = ID, xend =

...in real life. This approach will also make it clearer what really is going on. The effect of each of the timescales can then be modelled using the usual regression tools available in R. David Clayton har written an R-function that does it correctly, you can find it in: http://biostat.ku.dk/~bxc/Lexis/ along with its .Rd file. It is also included a Lexis-package which is a first shot at an epidemiology package for R available at http://biostat.ku.dk/~bxc/SPE/library/, but built under 1.9. I recently tried to build it under 2.0, but it crashed for me and I was advised to wait till 2.1 before I...

A new major upgrade of the Epi package for Epidemiological data analysis has been put on CRAN, it is now at version 1.0.7. It contains an entirely new way of representing follow-up data on multiple timescales and multiple states. See the function Lexis(). Plus a lot of other useful stuff for epidemiological analysis. See more on the package homepage, www.biostat.ku.dk/~bxc/Epi Note also that there will be a course 28 May - 2 June in Estonia, see www.biostat.ku.dk/~bxc/SPE.

I was wrong about needing the Relevel from the Lexis package. The default verson of relevel does the job of reshuffling levels in any desired order, albeit with a warning (which comes from the fact that apparently only a single number had been anticipated by the designer): > testf <- factor( sample( letters[1:4], 100, replace=T ) ) > tab...

Hi, I am traying to implement an STAR model, but I have some problems. I am following the instruction of the model, that they are in: http://bm2.genes.nig.ac.jp/RGM2/R_current/library/tsDyn/man/star.html that they are from: http://bm2.genes.nig.ac.jp/RGM2/pkg.php?p=tsDyn The model is: star(x, m=2, noRegimes, d = 1, steps = d, series, rob = FALSE, mTh, thDelay, thVar, sig=0.05, trace=TRUE,

Hi, Dear all R users: Does someone know whether R can calculate the Receiver Operating Characteristic (ROC) Curves? I didn't find it from the packages. Thanks a lot. --- Xin

Good day R-listers, I'm currently working on a panel data analysis (N=17, T=5), in order to check for the spurious regression problem, i have to ?test for stationarity but i've read somewhere ?that i needn't to test for it as ?my T<10 , what do you think? if yes ?is there any other test ?i have to ?perform in such case (a kind of cointegration test for small T?) Any hint would be

...e directory will still be on the server, even if it is empty (i.e. no dovecot index files in it). Of course, most people create folders and never delete them, but occasionally it's useful to do so. For the record, removing folders that contain messages (mbox files) works. -- William Astle Lexicom Ltd. Phone: +1-403-262-6610 Long Distance: 1-877-426-6277 Email: astle at lexi.net
