For a moment I thought I found another solution but I was wrong.
I don't think there is a conflict between this and installable package. It
won't help with the packaged version (but other packages depending on S4 suffer
from the same issue), but we can have an improved online version.
There is one possible alternative - converting all `names` to long
version:
```r
#' abs
#'
#' Computes the absolute value.
#'
#' @param x Column to compute on.
#'
#' @rdname abs
#' @name abs-method
#' @family non-aggregate functions
#' @export
#' @examples \dontrun{abs(df$c)}
#' @aliases abs,Column-method
```
This would keep CRAN checks happy and removed duplicates but at the cost of
having docs like this:

and making help unusable from R session, requiring:
?SparkR::`abs-method`
instead
?SparkR::abs
I am not sure if you agree, but IMHO this just makes things worse.
