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: http://tolstoy.newcastle.edu.au/R/help/06/01/19558.html But they didn't address this issue, down the thread. Thanks, Aravind.
