Thank you for reply,
I made some modification, the diff (against helpr 0.1.2.2)
is attached.
What I did are
1. Install helpr by install.packages()
2. Download the MathJax distribution and extract it under
$R_HOME/library/public/_script
3. Create a new html snippet file _mathjax_config.html in
the $R_HOME/library/view directory and then make index.html,
package.html, topic.html, source.html, and whistle.html
include the line
<%= helpr:::render_snippet("mathjax_config") %>
4. modify \\deqn part of th parse-rd.R from
"<code>... </code>" to "\\[ ... \\]"
and similarly, for \\eqn part from
"<code>... </code>" to "$ ... $".
The screenshot is also attached.
The rest question is, how to make R download the MathJax,
while install helpr?
Any comments are appreciated.
