[Rd] trace an Rd conversion error in R cmd check

[William Dunlap]

Good luck in tracking down the problem.  I won't give
any help there.

I've seen this sort of error message (or worse) when using
system.file() and the desired file didn't exist.  If that
is the problem, add the newish argument mustWork=TRUE to
the call to system.file so you get an error message from system.file
instead of a warning or inappropriate behavior from the function
that is confused by the "" that system.file() returns when the
desired file doesn't exist.

  > con <- file(system.file(package="base", "noSuchFile"), "r")
  Warning message:
  In file(system.file(package = "base", "noSuchFile"), "r") :
    file("") only supports open = "w+" and open = "w+b": using the former
  > con <- file(system.file(package="base", "noSuchFile", mustWork=TRUE), "r")
  Error in system.file(package = "base", "noSuchFile", mustWork = TRUE) : 
    no file found
