# Script to create API docs and vignettes for SparkR
# This requires `devtools`, `knitr` and `rmarkdown` to be installed on the machine.

# After running this script the html docs can be found in 
# $SPARK_HOME/R/pkg/html
# The vignettes can be found in
# $SPARK_HOME/R/pkg/vignettes/sparkr_vignettes.html

# Install the package (this will also generate the Rd files)

# Now create HTML files

# knit_rd puts html in current working directory
