[Rd] problems with new checks in R-devel

Below are a few problems I have encountered with the new checks
being done in R-devel.
1/ I have two generics, test.equal and test.equal.tframe. The
first checks that two objects are equal while the second checks
if two objects have equal tframes (time frames). There is no
reason these should have similar arguments but the check seems to
think that test.equal.tframe is a method for test.equal so I get:
* checking generic/method consistency ... WARNING
test.equal:
function(obj1, obj2, ...)
test.equal.tframe:
function(tf1, tf2)
2/ I have some generics which may or may not already be defined
(e.g. lag would be defined if library ts is attached) so in my R
code I use
if (!exists("lag")) lag <- function(x, ...) { UseMethod("lag") }
but this results in
Objects with usage in file `.../tframe/man/lag.tframe.Rd' but
missing from code:
[1] "lag"
Is there a better way to approach this in my R code so I don't
get these warnings?
3/ I have a few general introduction .Rd files which do not
have a usage line and they produce
* checking for undocumented arguments in \usage ... WARNING
Error in parse(file, n, text, prompt) : parse error
Error in checkDocArgs(dir = ".../syskern") :
cannot source usages in file
.../syskern/man/00Intro.syskern.Rd
Execution halted
Should that be expected or is it a bug?
