[R] Rpad - avoid removal of manually created html-tags in R chunk
Dear Rpad-users,
currently I am setting up a web page using Rpad (www.rpad.org). But I
have a problem with generating dynamic html-output in the Rpad chunk.
Here an example of my problem:
I have the following index.html file:
<html>
<head>
<title>example</title>
<meta http-equiv="Content-Type" content="text/html;
charset=utf-8">
<script type="text/javascript"
src="gui/Rpad.js"></script>
</head>
<body>
<pre dojoType="Rpad" rpadRun="init"
rpadOutput="html"
rpadHideSource="true">
x <-
"<table><tr><th>A</th><th>B</th></tr><td>a</td><td>b</td></table>"
</pre>
</body>
</html>
If I run Rpad("index.html") in the local server mode and when I turn
to
my Rgui, then the object "x" looks like "ABab", i.e. all my
html-tags
are removed within the R-chunk.
I know that I can avoid this with nested "HtmlTree"s, e.g.
H("table", H("tr", H("th", "A"),
H("th", "B")), H("tr", H("td",
"a"),
H("td", "b")))
but as I have to produce html-output of a large dataframe (100 rows and
6 colums), the nesting takes too much time (because every cell element
might have conditional formatting and I have to check each element) and
I think it would be faster with pasting all html-code manually into a
character-object and printing this object as html. But trying this I
have the above mentioned problem.
Can anybody help me? If anybody knows a solution, how I can avoid, that
the html-tags are removed from my "x" (see example above), I think, I
can produce my output very fast.
Thanks and best regards,
Martin
