Hi all,
I've been trying out the code from Chamber's "Classes and Methods
in the S
language":
http://www.omegahat.org/RSMethods/Intro.pdf>From my session:
R> whatis <- function(object) paste( "sdw" )
R> setMethod( "whatis", "vector", function(object) paste(
"cswdvcr" ) )
R> dumpMethod( "whatis", "numeric" )
[1] "whatis.numeric.R"
But the "whatis.numeric.R" file contains:
setMethod("whatis", "numeric",
NULL
)
As you can see this is not what the guide describes. My R environment( built
from source ):
R> sessionInfo()
R version 2.6.0 (2007-10-03)
x86_64-unknown-linux-gnu
locale:
LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=C
attached base packages:
[1] stats graphics grDevices utils datasets methods base
loaded via a namespace (and not attached):
[1] rcompgen_0.1-15 tools_2.6.0
My Linux( uname -a):
Linux hostname 2.6.18.8-0.7-default #1 SMP Tue Oct 2 17:21:08 UTC 2007
x86_64 x86_64 x86_64 GNU/Linux
When searching the list-archives, I found a similar situation:

But they didn't address this issue, down the thread.
Thanks,
Aravind.
