[R] Sending a matrix in an email

[Jeff Newmiller]

No, sorry to flog a dead horse, but you do not appear to get it yet and you really should understand this concept.  The minimal reproducible example would have been R code that we could run that generated an email that you think should have the matrix in it, but does not. In practically all help queries on this list we should be able to run your code and see the not-desired behavior.
