...-maintained package "methods" Hello, I have found that I cannot use sealClass() without specifying the 'where' argument. I have found this issue in R 3.2.3 and R 3.4.0. For example: > setClass("foo", slots=c(name="character", age="integer")) > isSealedClass("foo") [1] FALSE > sealClass("foo") Error in list2env(list(<environment>), NULL, <environment>) : names(x) must be a character vector of the same length as x > isSealedClass("foo") [1] FALSE > sealClass("foo", where=.GlobalEnv) > isS...

...o determine the nearest top level environment (usually .GlobalEnv or a name space environment). - Added name space support for packages that do not use methods. o Formal classes and methods can be `sealed', by using the corresponding argument to setClass or setMethod. New functions isSealedClass() and isSealedMethod() test sealing. o packages can now be loaded with version numbers. This allows for multiple versions of files to be installed (and potentially loaded). Some serious testing will be going on, but it should have no effect unless specifically asked for.
