DiagrammeR example leads to 'could not find function "%>>%" ' error

In R 3.2.0 on Windows, running the example code titled

"An Example with Data from the nycflights13 Package"

from

https://github.com/rich-iannone/DiagrammeR

leads to

Error: could not find function "%>>%"

Full, reproducible example:

I have tried this with both the CRAN and development versions of DiagrammeR and I tried reinstalling Rgraphviz but the results did not change.

Per @DavidArenburg's comment, the %>>% operator is from the pipeR package. Install it with install.packages("pipeR") and then library(pipeR) and the code should work.

Note that %>>% is a pipeline operator. One could also use the single > operator, that is %>%, from the magrittr package. For an excellent write-up on the differences, see this link
