[R] Sending a matrix in an email

[Ira Fuchs]

I have a matrix which has colnames and I would like to send this matrix using sendmailR. How can I convert this simple matrix to a format which can be used as the body variable in sendmailR? I see how I can create a file attachment using mime_part but I would like to send the matrix in the body of the email. 

The matrix looks like:

      ABD  DEF  GHI  JKL MNO   TOT 
[1,] 0.44 0.81 1.67 0.37 0.31 -1.18


All the conversions I have tried end up sending the matrix without the colnames.

Thanks.
