\everypar={\hangindent=9mm}

\bcode{HTML(x)} outputs an HTML representation of an object (uses
package \code{R2HTML})

\bcode{HTMLon()}  turn on HTML mode (the default is text)

\bcode{HTMLoff()}  turn off HTML mode

\bcode{HTMLtag(tagName, ...), HTMLetag(tagName)} make starting and
ending tags for \code{tagName} with ... elements as tag parameters

\bcode{HTMLh1(text), HTMLh2(text), ...} headings H1, H2, ...

\bcode{HTMLargs(...)} a string with the arguments as \code{"a='arg1'}
  \code{b='arg2'"}, and so on

\bcode{HTMLradio(variableName, commonName="radio", text="")}
  a radio input with an R variable name
  \code{variableName}; \code{commonName} links it with other radio
  elements; \code{text} specifies an adjacent label

\bcode{HTMLcheckbox(name, text="", checked=FALSE)}
  a checkbox input with an R variable name \code{name}

\bcode{HTMLselect(name, text, default=1, size=1)}
  a select box with an R variable name \code{name}
  with the options \code{text}

\bcode{HTMLinput(name, value="", rpadtype="Rvariable")}
  an input box with an R variable name \code{name} and
  default \code{value};
  \code{rpadtype} can by \code{"Rstring"} or \code{"Rvariable"}

\bcode{HTMLlink(url, text)}
  a link wrapped around \code{text}

\bcode{HTMLimg(filename)}
  an img

\bcode{HTMLembed(filename,width=600,height=600)}
  an embed (useful for pdf or svg)

Most of these return a character string, and
automatic printing sends the string to the output with the
effect that the HTML is displayed in Rpad. 


\section{Rpad plotting utilities}
\everypar={\hangindent=9mm}

\bcode{newgraph(name="",...)} sets up the graphics device (not needed unless you
want to change parameters)

\bcode{showgraph()} generates the HTML to show the graph and runs
\code{newgraph} to advance
to the next graphics file; \code{link=TRUE} creates a link to the EPS file

\bcode{graphoptions(...)} changes the defaults for subsequent graphs

\everypar={\hangindent=0mm}
\code{newgraph} and \code{graphoptions} have the following options
with the defaults given: \code{type="pngalpha", res=120,
width=3.5, height=, pointsize=10, sublines=0,
toplines=.6, ratio=4/3, leftlines=0, lwd=0.6}
