...like to create a [start,stop] pair of vectors that index the first and last observation per ID. For the ID list above, it would look like 1 1 2 3 4 6 7 7 8 9 I haven't worked with indexes/data manipulation much in R, so any pointers would be helpful. Many thanks! ~~~~~~~~~~~~~~~~~~~ -Robin Jeffries Dr.P.H. Candidate in Biostatistics UCLA School of Public Health rjeffries@ucla.edu 530-624-0428 [[alternative HTML version deleted]]

Hi list! I have prepared a custom function (below) in order to calculate separability indices (Divergence, Bhattacharyya, Jeffries-Matusita, Transformed divergene) between two samples of (spectral land cover) classes. I need help to cross-compare results to verify that it works as expected (since I don't know of any other foss-tool that will give me quickly some results). Does anybody use another mean/tool/function...

I've calculated as follows: matusita<-function(f1,f2,lw,up){ fmatu<-function(x) ( sqrt(f1(x)) - sqrt(f2(x)) )^2 sqrt (integrate( fmatu, lower=lw, upper=up, subdivisions=1000000)$value) } Josué Almansa Unitat de Recerca en Serveis Sanitaris Institut Municipal d'Investigació Mèdica, IMIM c/ Doctor Aiguader, 80 08003 Barcelona e-mail: jalmansa@imim.es

...2 measurements ... subject.value[5] <- sum(value[11:15]) # the next 5 measurements I'd imagine it'll be some sort of *apply(value, nrep, sum) but I can't seem to land on the right format. Can someone give me a heads up as to what the correct syntax and function is?

Hi, I have a somewhat complicated relationship question. I''ve been banging my head about this for some time and have given in and decided to ask the list :) Here''s what I''m trying to achieve: Products can have variants. For example, a t-shirt could come in small, medium and large, but also black, green and blue in the first two sizes, but only blue in large.

...d a(t), b(t-1) and c(t-1) into FUN2 to simulate b(t) and c(t). I'd love to have one core run FUN1 and another run FUN2, and better yet, a third to run all the pre-and post- processing tidbits! So if anyone has any suggestions as to a direction I can look into, it would be appreciated.

I''d like to ask for clarification on the upgrade procedure using tarballs. In the past, with version 4.4, I have downloaded shorewall-4.4.x.y.tar.bz2 and shorewall6-4.4.x.y.tar.bz2, extracted each, and executed ''install.sh -s'' in each directory. Now there is a new package shorewall-core-4.5.x.y.tar.bz2. As I understand it, with version 4.5, this core package needs to be

...list(rep("character",7),0,"logical",0,"character")) to use in scan(), it still read everything in as character. I'm also not sure about the "" 's, I had to put them in to get list() to even accept that. Or c(). Any ideas with this? Thanks! -- Robin Jeffries Dr.P.H.
