[R] R CMD check failure on minimal code

[Prof Brian Ripley]

Did you remember to declare a dependency on package 'methods'?  I suspect 
not.  Please see `Writing R Extensions'.

setClass is not part of base R, and those checks are being run with base 
R only.  I expect your package will not load when R is run with no default 
packages.  (Quite a few people run R without package 'methods' for 
speed, especially on startup -- it takes about half the startup time.)
