 - If you are using the CRAN version, when you run rmarkdown from console using RScript, you need to include `library(methods)` at the begining due to a `rvest` issue. By default, `library(methods)` is loaded in R GUI and RStudio. I eliminated the step requires `rvest` in current github version since it doesn't provide a very useful feature. See [this SO post for details](http://stackoverflow.com/questions/35351443/rvest-html-nodes-error-cannot-coerce-type-environment-to-vector-of-type-l). Thanks twitter user @Gimperion for reporting.
