Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using R 2.8 with lattice 0.17-15 *** To replicate the bug: 1.- display an xyplot. For example, from the xyplot help page:

hello! je veux importer un fichier de donnees excel que j'ai au prealable converti en fichier txt avec separateurs tab, fichier de la forme entree simple (suite de colonnes contenant des variables).

...rm (POSIXlt) By example : ctDate<-1132963200 #"Wed Aug 30 14:24:37 2006" is(ctDate) [1] "numeric" "vector" ctDate isn't a numeric vector, it is a POSIXct... none of the clues inside the docs has given me the answer, i can't cast it, i can't converti t to POSIXlt because it is wrong class (as.POSIX** don't want to work...) What is the trick ?? Any ideas would be great thks COMTE Guillaume [[alternative HTML version deleted]]

...recommened in writing R extensions rexit(message). I'm working with a very large legacy program which was developed over 16 years and I am reluctant to rewrite the entire error handling sections in R. I was wondering if anyone has gotten CRAN to accept a package with a Fortran write statement converting numbers to characters or if anyone has found another method for doing type conversion in Fortran without the "write" statement.

Dear all, In an attempt to draw fill patterns in grid graphics, I have encountered a behavior of grobX that I cannot understand from the documentation. Consider this, library(grid) ## gTree g1 <- gTree(children=gList( rectGrob(0.5,0.5, width=unit(0.8,"npc"), height=unit(2,"cm")), circleGrob(r=0.3)), vp=viewport(0.5,0.5)) ##

Dear list, Following a recent enquiry, I've been playing with the idea of creating a colour gradient for a polygon, using the Grid package. The idea is to draw a number of stripes of different colours, using the grid.clip function. Below is my current attempt at this, library(grid) rotate.polygon <- function(g, angle=0){ # utility function, works fine matR <- matrix(c(cos(angle),

In a string context, grep, gsub, sub are improperly treating NA (missing) as the string "NA", and returning unexpected results > grep("A", c(NA,"NA")) [1] 1 2 # expected: # [1] 2 > gsub("A", "X", c(NA,"NA")) [1] "NX" "NX" # expected # [1] NA "NX" > sub("A", "X",

Does anyone know how to import a SAS .sd2 file into R? I can't see anything in library(foreign). Thank you. Mark

Hi all, I am back with a new question ! I recorded the occurence of 4 differents event on 20 places for a given time period. Now, I want to do some barplot of the frequency of theses events for each place, so it should be easy. My problem is that I want to see the frequencies of the 4 events on my barplots even if the frequency of some of them is 0. How could I do that ? Thanking you in advance

Hi, I am falling in love more and more with RoR. I am looking for a Book/Tutorial which teaches me creating an excellent WebSite for dating and Classified. I am coming from .net community and now willing to grow more with ROR. We used to have few starterkits in .Net. Can any one provide me an excellent guideline, how is it possible. Is there any tutorial site, which offers scripts to study
