I'm trying to use function "solve" to find the inverse of a matrix, which is
positive definite in theory. But for some situations, I get error message
because of computational singularity. I'm wondering if I can set the
tolerance for detecting linear independence to an infinitely small value to

Using slot() on object (or "@") and using a nonexistent
slotname returns an error (see example code).

I agree. Furthermore I think it might be useful to add that in my
experience (and I'm sure others as well) that the process of creating
a simple reproduceable example for an email to r-help will in most
