On this note can we update the roxygen doc for DataFrames ? http://spark.apache.org/docs/latest/api/R/DataFrame.html seems pretty incomplete.

[felixcheung]

why don't we point to http://spark.apache.org/docs/latest/sparkr.html for now instead?

[Lewuathe]

@felixb Other docs for Scala, Java and Python toward API documents. So I thought it might be better to make it indicate toward http://spark.apache.org/docs/latest/api/R/DataFrame.html too.

[shivaram]

Yeah but the DataFrame.html doesn't seem very useful the way it is right now -- can you just update the roxygen docs in this PR as well ?

[Lewuathe]

@shivaram Sure. I'll submit.

[Lewuathe]

This failure does not seem to be related to the patch.

[shivaram]

Jenkins, retest this please

I think this error is related

First time using roxygen2 4.0. Upgrading automatically...
Error: Failure in roxygen block beginning DataFrame.R:23
Mismatched braces: "@seealso \{createDataFrame}, \link{jsonFile}, \link{table}"
Execution halted

[felixcheung]

it should be @seealso \link{createDataFrame}

The latest error is

Error: Failure in roxygen block beginning DataFrame.R:23
@export may only span a single line

@Lewuathe you can verify this locally using ./R/create-docs.sh before submitting to Jenkins

[Lewuathe]

@shivaram Thank you. But that error was not occurred on local. Only warning and generating process ended up successful. Anyway I can update it.

I'm not sure we need to modify this file in this PR - It encodes some dependencies among R files which is sometimes fragile.

[shivaram]

Thanks @Lewuathe -- LGTM. This is good to go if you can revert the change to the DESCRIPTION file.
