[SPARK-18825][SPARKR][DOCS][WIP] Eliminate duplicate links in SparkR API
doc index
## What changes were proposed in this pull request?
Duplicate links come from the `00Index.html` created during package
installation. The file has a regular structure, where each link is a table
row, slitted into two lines:
```r
<tr><td style="width: 25%;"><a href="atan.html">atan-method</a></td>
<td>atan</td></tr>
```
This PR adds an additional steps to the `R/create-docs.sh`:
- Copy `00Index.html` to the current working directory;
index_path = file.path(libDir, "SparkR", "html", "00Index.html");
invisible(file.copy(index_path, "00Index.html.bck"));writeLines(txt,
index_path);
- Reads file and removes problematic lines
txt = readLines(index_path); method_lines = grep("-method</a>", txt,
fixed = TRUE);
txt = txt[-c(method_lines, method_lines + 1)];
- Writes file back:
writeLines(txt, index_path)
- Executes current pipeline.
- Restores original content:
invisible(file.rename("00Index.html.bck", index_path))
Arguably this is not the most reliable approach, but doesn't require any
parser, and can be embedded in the current `create-docs.sh`
## How was this patch tested?
Manual inspection of the docs.
