> We are currently converting dots to underscore in some cases as below in SparkR
> {code}
> > createDataFrame(list(list(1)), "a.a")
> SparkDataFrame[a_a:double]
> ...
> In FUN(X[[i]], ...) : Use a_a instead of a.a  as column name
> {code}
> {code}
> > createDataFrame(list(list(a.a = 1)))
> SparkDataFrame[a_a:double]
> ...
> In FUN(X[[i]], ...) : Use a_a instead of a.a  as column name
> {code}
> This looks introduced in the first place due to SPARK-2775 but now it is fixed in SPARK-6898.
