A way to send gmail message from R with attachments.
Currently there isn't a release on CRAN.
You can, however, download the zip ball or tar ball, decompress and run R CMD INSTALL
on it, or use the devtools package to install the development version:
# install.packages("devtools")
library(devtools)
install_github("gmailR", "trinker")
Note: Windows users need Rtools and devtools to install this way.
