tapply on empty data.frames (PR#10644)
Full_Name: Hilmar Berger Version: 2.4.1/2.6.2alpha OS: WinXP Submission from: (NULL) (84.185.128.110) Hi all, If I use tapply on an empty data.frame I get an error. I'm not quite sure if one can actually expect the function to return with a result. However, the error message suggests that this case does not get handled well. This happens both in R-2.4.1 and 2.6.2alpha (version 2008-01-26).

problem with --vanilla in R
Hallo, I'm using the R Version 2.3.0 (2006-04-24) on Suse Linux 10.1. With an older R and Linux version I could write a R-function into a file and execute it with the command: R --vanilla < script.r In the file script.r was code like this: postscript(file="results.eps") x<-2 y<-3 plot(x,y) dev.off() It worked fine, but now nothing happens. In the manual page this option

ifelse drops classes
Hi all, I guess that this is rather a feature request than a bug report, but I'm not really sure: I stumbled over this today (R 2.6.2, WinXP): > c=c(as.Date("2007-01-01")) > class(c) [1] "Date" > ifelse(is.na(c),as.Date(Sys.time()), c) [1] 13514 > typeof(ifelse(is.na(c),as.Date(Sys.time()), c)) [1] "double" >
