[rkward-users] rkward output issues [TOC and plot parameter modifications].

[Sourav Chakraborty]

Hi Thomas,

Thanks for your quick response. 

I changed the font size using view-> enlarge/shrink font. However, it is
a control over global font size, therefore all the fonts are changed
including TOC fonts. My table fonts were smaller earlier and now it is
harder to read them. The reason I want to change them is because because
of the size and spacing, some information do not fit in one page (empty
space).

I see that I was using the term "output" superficially. My apologies and
a clarification. I absolutely love the output in the "On-screen
graphics" (I can manipulate and create any size graph I want, this is
one of the main reason I love using RKward). My problem is the
rk_out.html. 

The development version has some support for adding custom HTML-headers
to the 
output document, e.g. a custom CSS-definition. If it really bugs you,
you 
could also modify the (extremly basic) default CSS file we ship. Use
View->View Document Source on the output window to find out where this
is 
located on your system.

First of all, I appreciate what you are doing for free. I will not say
that anything about this software bugs me. However, I was wondering if
there is a flexibility as it is a open source development project. And
you already mentioned that I can create a custom CSS. I have done some
searching and found out that I should manipulate the following code.
Unfortunately, I have no knowledge about CSS manipulation. A little
reading did not help me. It would be great if you can enlighten me about
how and where I can incorporate level 1 font 14 point (bold) spacing (6
above 3 below) in the following code (and if I want to change level 2
fonts where should I define it).

pre.code {
	margin-left: 2em;
}

pre.code:before {
	display: block;
	content: "> ";
	width: 2em;
	color: black;
	float: left;
	margin-left: -2em;
}

pre.output_normal {
	clear: both;	/* make sure never to float around the "> " marker */
}

pre.output_warning {
	clear: both;	/* make sure never to float around the "> " marker */
	background-color: #ffaaaa;
}

table {
	border-spacing: 0px;
}

/* TOC menu */
.RKTOC {
	background-color: #eeeeff;
	position: fixed;
	top: 0px;
	right: 0px;
	height: 100%;
	width: 25%;
	padding: 7px;
	display: none;
	overflow: auto;
}

.RKTOChidden {
	display: inline;
height: 1em;
	overflow: hidden;
}

.toggleTOC:link, .toggleTOC:visited {
	color: blue;
	font-weight: bold;
}

.right {
	position: absolute;
	right: 7px;
	text-align: right;
}

.center {
	position: absolute;
	right: 25%;
	left: 25%;
	top: 7px;
	text-align: center;
}

/* end TOC menu */



I did not actually try this code (if you can, please try to condense
your examples to the absolute minimum, 
and use data from the datasets-package; this really saves us valuable
time), and maybe I did not understand the problem. 

I apologize for providing my own scripts and data. I understand the
inconvenience and will address it in subsequent posts.

Let me try to clarify one more time. If a script loops through my
columns to create graphs for each column, is there a way to keep the
graphs in the
R graphics window (I have done this before, however, now I only see one
graph at a time when I run my script).

Thank you once again for following up in detail.

I will look forward to hear back from you.

Best,
Sourav
