Dear R-Devel subscriber, I was hinted to the following problem with package 'urca':
If one starts R and executes for instance: > library(urca) > example(ur.df) ## output as expected, but omitted here > class(lc.df) [1] "ur.df" attr(,"package") [1] "urca" > class(summary(lc.df)) [1] "sumurca" attr(,"package") [1] "urca" > everything works fine. Now, save the workspace image and quit R. After starting R again with the previously restored workspace image one has: > ls() [1] "lc.df" "Raotbl3" > class(lc.df) [1] "ur.df" attr(,"package") [1] "urca" lc.df ## now the 'show'-method for objects of class 'ur.df' is not utilised, rather the generic ## displaying all slots > library(urca) > lc.df ## still the same as compared to the above output. ## similarily > class(summary(lc.df)) [1] "table" In the NAMESPACE file export directives for methods and classes are included as: ## Classes exportClasses("urca", "ca.jo", "cajo.test", "ur.kpss", "ca.po", "ur.ers", "ur.pp", "ur.sp", "ur.df", "ur.za", "sumurca") ## Methods exportMethods("show", "plot", "summary") Any help or pointers for solving this problem is much appreciated.
