RTD is an official R client for Arm Treasure Data. It aims to make it simple to handle or connect from R to TD.

If you want to use embulk, ensure you've installed embulk and set PATH for it.
As of version 0.4.1, RTD has been back to CRAN. You can install RTD as:
You can install via devtools::install_github for the latest development version.
install.packages("devtools") # Install devtools if needed
devtools::install_github("treasure-data/RTD@v0.4.1")
Or, you can use install-github.me instead like:
source("https://install-github.me/treasure-data/RTD@v0.4.1")
