Problem with Rcmd check and S4 methods

It would be nice to be able to get a dump from the R CMD check
evaluation--maybe someone can suggest how.

If I just cut all the preamble from the Rout file and paste it into
the console, I get the same error.  Here's a traceback(), I'm not sure
what you mean by a dump.

 x <- eulerzyx(1,0,0)

Error: Trying to get slot "validity" from an object of a basic class
("NULL") with no slots

traceback()

5: validObject(.Object)
4: initialize(value, ...)
3: initialize(value, ...)
2: new("eulerzyx", x = cbind(psi, theta, phi))
1: eulerzyx(1, 0, 0)
