[Tex/LaTex] Resize Arrays and Figures in a Sweave document.

beamersweave

How is it possible to resize figures produced via a Sweave script?

I tried scalebox and others, but I can't succeed to obtain a figure with an acceptable size in my beamer with direct Sweave output like:

<<MyGraph,fig=T>>
x <- rnorm(1000)
y <- rnorm(1000)
plot(x,y)
@

Good answers for figures but for text output ? (see below)

I would also like indications to resize for example an output which is too large for the screen.

For example:

<<MyBigData.Frame,echo=off>>
summary(mybigdata.frame)
@

For the figures something like,

«MyGraph,fig=TRUE,height=4,width=8»= 
…
@

should work. (It defaults to inches.)

To set the default size of all figures in the document with respect to the text block, try, e.g.,

\setkeys{Gin}{width=0.9\textwidth}

You can set absolute widths (in inches or cm) that way, too.

[Tex/LaTex] Supplying string parameters to Sweave document

there are two ways to do what you seek. one is using sweave, the other is using an R package called brew which overcomes sweave's limitations of looping over a global variable. i am providing both code chunks.

The Sweave Code Chunk

\begin{document}
<<echo = F, results = tex>>=

figdir   = paste(getwd(), 'fig', sep = '/')
fignames = read.csv('fignames.csv');
for (i in seq_along(fignames)) {

 filename = file.path(figdir, i)

 cat("\\pagebreak");
 cat("\\section{", i, "}", sep = "");
 cat("\\begin{figure}[htbp]");
 cat("\\caption*{MyCaption", i, "}", sep = "");
 cat("\\includegraphics[width = 0.5\\textwidth]{", filename, "}", sep = "");
 cat("\\end{figure}");
}
@

\end{document}

The Brew Code Chunk

\begin{document}
<% figdir   = paste(getwd(), 'fig', sep = '/') %> 
<% fignames = read.csv('fignames.csv');
<% for (i in seq_along(fignames)) { -%>

\pagebreak

<% filename = file.path(figdir, i) %>  
<%= cat("\section{", i, "}", sep = "") %>

\begin{figure}[htbp]
\caption*{MyCaption}

<%= cat("\\includegraphics[width = 0.5\\textwidth]{filename}")

\end{figure}
<% } -%>
\end{document}

you can check out the link to brew on how to use it from R

EDIT: this would produce a single file with all the output.

[Tex/LaTex] Size of Sweave Output

You can use the \scalebox{} command that comes with the graphicx package. E.g., with

\scalebox{0.7}{%
\begin{tabular}{...}
...
\end{tabular}}

your text will be printed at 70%.

This will only work if you use a Sweave chunk to create an external file (say, tab1.tex) and then include it in the LATEX file using an \include or \input statement, not by printing it directly into you master file with results=tex.

Update:

Given my comment and your updated question, I would suggest to look at the Design package which offers convenient LaTeX export of nice-looking Tables, see summary.formula(). Again, the idea would be to write a Table generated this way into a TeX file, and then \input it into your master Rnw file. You can look at Statistical Reporting, Linking S Output with Report Documents, Literate Programming, Managing Analyses, and Documenting Programs and Data for more detailed illustrations.
