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).

strange behavior of cor() with pairwise.complete.obs
Hi all,
I'm not quite sure if this is a feature or a bug or if I just fail to understand
the documentation:
If I use cor() with pairwise.complete.obs and method=pearson, the result is a
scalar:
->cor(c(1,2,3),c(3,4,6),use="pairwise.complete.obs",method="pearson")
[1] 0.9819805
The documentation says that

To load Add-ons
Dear R Help-Team,
If I start R and type in
search()
the result is:
[1] ".GlobalEnv" "package:ctest" "Autoloads" "package:base"
I often need an Add-on-package. I can load it with "> library(package)" or
include a require-command in the .First-function. The .First-function is
fine, if I always use the same working directory. But I

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"
