Sirs:
My validity function did not run when my class contains="matrix". But if I
first define the class with contains="numeric", then define it again
with contains="matrix", validity runs. Here's the session:
> f <- function(object) "BAD CLASS" # force error to
> setClass("A", contains="matrix",

If I go to:
http://r-forge.r-project.org/scm/?group_id=18
and click on [Browse Subversion Repository] in the box to the right it
takes me to a page that says this:
Traceback (most recent call last): File

system.time(ave(d$x, d$grp1, d$grp2, FUN = mean))

Try this:
replace(x[1][], TRUE, NA)
or
replace(x[[1]][], TRUE, NA)
depending on what you want.

That's pretty close, but it doesn't fail nicely for non-atomics:

Error in as(NA, class(Sys.Date())) :
no method or default for coercing "logical" to "Date"
vs.
> as.Date(NA)
[1] NA
But I'm probably being too fus
What about NAof <- function(x) as(NA, class(x))?

I just do as.integer(NA), as.numeric(NA), as.character(NA), etc.

Hi all,
Is there an existing function that provides the correct type of
missing value for a given vector? e.g.
NAof(1:3) # NA_integer_
NAof(pi) # NA_real_
NAof("a") # NA_character_
NAof(T) # NA
?
Thanks,
Hadley

Yes, that's essentially what I use (except the shlib flags).

Thanks again for your note. I am now compiling using:

--with-blas="-llibptf77blas -lpthread -llibatlas" --prefix=/usr/local/R-2.11.0
The above configuration is creating libRlapack.so as well. Do you specify
--with-lapack as well? If so, wha
