Sending a matrix in an email

Thanks for the suggestion. I just tried dput and it did not produce what sendmailR requires for the body parameter. Here is a simplified version of what I need to do:

x=matrix(c(1,2,3),1,3)
x

   [,1] [,2] [,3]
[1,]    1    2    3

colnames(x)=c("a","b","c")
x

   a b c
[1,] 1 2 3

dput(x)

structure(c(1, 2, 3), .Dim = c(1L, 3L), .Dimnames = list(NULL,
  c("a", "b", "c")))

I want to send x in sendmailR(to,from,x) and have it look more or less like the output above. Simple, right?

After this at the console:

sink("myfile.txt")

x=matrix(c(1,2,3),1,3)
x
colnames(x)=c("a","b","c")
x
sink()

I get this in myfile.txt:

    [,1] [,2] [,3]
[1,]    1    2    3
    a b c
[1,] 1 2 3

There is also a capture.output function.

What about dput()?

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.
