Suppose I have a list of logicals, such as returned by lapply: Theoph$Dose[1] <- NA Theoph$Time[2] <- NA Theoph$conc[3] <- NA lapply(Theoph,is.na) Is there a direct way to execute logical "or" across all vectors? The following gives the desired result, but seems unnecessarily complex. as.logical(apply(do.call("rbind",lapply(Theoph,is....

Hi, everyone, Try the following command to see if you get TRUE or FALSE. I get FALSE on a unix platform but TRUE on Windows. Any comment? all(paste(Theoph[1],Theoph[2])==paste(Theoph[[1]],Theoph[[2]])) -- Jun Shen PhD PK/PD Scientist BioPharma Services Millipore Corporation 15 Research Park Dr. St Charles, MO 63304 Direct: 636-720-1589 [[alternative HTML version deleted]]

Dear all, I tried to create a groupedData object, where the grouping factor is not ordered. Here ist the code: library(nlme) test<-groupedData(conc~Time|Subject,order.groups=F,data=as.data.frame(Theoph)) > getGroups(test) Levels: 6 < 7 < 8 < 11 < 3 < 2 < 4 < 9 < 12 < 10 < 1 < 5 I still get an ordered factor. As always thanks for your help peter -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http...

Dear all, This question was asked a few years ago. Back then, the answer was NO. Just wonder if the package has been updated to make it possible. An example (Theoph is a dataset coming with R) ggplot(data=Theoph, aes(x=Time, y=conc)) + geom_point() + facet_wrap(~Subject) gives me all 12 subjects on one page. Can I break it down to several pages? say 2x2 on each page? Thanks. Jun [[alternative HTML version deleted]]

...a" to control margin size even on a trelllis plot (see the plot below). However, it does not seem to work in R. All suggestions will be highly appreciated.

Dear all, I am trying to gain some experience with the function gnls from the nlme package. I tried to model the Theophyline data by trying to model the presumed dependency of the clearance on the body weight. This is my function call of gnls: gnls(conc~SSfol(Dose,Time,lKe,lKa,lCl),data=Theoph, params=list(lKe~1,lKa~1,lCl~Wt),start=c(-2.4,0.46,-3.22,0.01)) That's been the result: Error in as.vector(x, mode)...
