It works for me: X <- setRefClass("XXX", fields = list(a = "character")) X$accessors("a") X # ... # Class Methods: # "callSuper", "export", "getA", "import", "initFields", "setA" # ... accessors() convenience method creates setA and getA functions: x <- X$new() x$getA #Class method definition for method getA() #function () #a #<environment: 02a198c0> HTH, Vitalie. > > > Thanks a lot, > > Janko > > [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
