returns the last item in the collection -

pdf/writer: table.render_on best practices?
Hi All,
I generate a pdf report that contains a table. The report is 14 pages, and
it takes 20s to be rendered. Most of these 20s are spend in the render_on
method. I wonder if it is possible to speed up that process?
To create the report, I do the following:
1) Setup pdf layout:
# Setup pdf layout
pdf.select_font("Helvetica", { :encoding => "WinAnsiEncoding"})

Hi R users.
I've got a problem in producing the pdf file from Latex with R code. When I

Limit to the number of draggables?
I''m wondering if there''s a max number of draggables. I have a
situation where there are something like 60-80 draggable items and
they work fine on the test server with only a handful of items, but in
production with the full load they no longer work. It''s possible
there''s something else different -- somehting with style sheets or
something, but I wanted to see

PCA loadings differ vastly!
hi, I have two questions:
#first (SPSS vs. R):
I just compared the output of different PCA routines in R (pca, prcomp,
princomp) with results from SPSS. the loadings of the variables differ
vastly! in SPSS the variables load constantly higher than in R.
I made sure that both progr. use the correlation matrix as basis. I
found the same problem with rotated values (varimax rotation and rtex=T

Possible to scroll window when user drags a draggable?
It doesn''t seem to be possible, but perhaps somebody knows a trick. I
have some lists that get too long and users can''t drag from list 10,
for example, to list 1. Is there a way to get the browser window to
scroll as they drag the item up?
Thanks!

PDF::SimpleTable performance issues
Hello,
I am having performance issues ending with a ''time out'' from Apache when
I try to generate a PDF file using pdf-writer.
It seems to happen at the render_on(pdf) function call ; the table I am
trying to draw has 8 colums which values are generated on the fly.
Can''t find anything about pdf-writer and the ''time out'' on the Web so
far.

Looking for knitr example for beginner (NO RStudio)
Hi everyone,
I am using package knitr, FIRST TIME. I don't have access to RStudio.
Read through Yihui's page, didn't find it helpful. Stuck on terms

How to have multiple fields appear in collection_select?
I have a table of employees with the fields "last_name" and
"first_name". I would like to populate a collection select so that what
the user sees in the drop-down is "Last Name, First Name". So far, the
only way I have figured out to do this is by using "find_by_sql" in my
model, like so:

Deploying in Dreamhost
What pain. I am ready to switch hosts. I have this app in Dreamhost
where I load the static pages just fine. The location of my rails app
is /home/username/webaddress.com Under that resides the app/, public/

comparing distributions
I have data sets from three different sites. None of the data sets are
normally distributed and can not be log-transformed to a normal
distribution. I would like to compare the data sets to see if any of
the sites are similar to each other, and would like something more
powerful than a non-parametric wilcoxen test. Does anyone have any
suggestions on more powerful ways of comparing non-normal data

convert HTML to LaTeX or text
Hi all,
I have a RoR app which can output a report in HTML back to the web browser, or
(preferably) in PDF using the RTex plugin. I have a number of text fields which
are stored as HTML, and am looking for a good way to convert them to something
LaTeX-compatible, or plain text if that''s the last resort. I''ve seen a number
of html2tex-type converters out there, but they are by

Sweave echoing comments (again)
Hello,
I try to document some R scripts for my collegues and observed the
problem, that Sweave strips comment lines away.
As a small example I write in an Rtex file:
\begin{Scode}
## a small example
test() # line comment
\end{Scode}
... the .tex file generated by Sweave only contains:
\begin{Schunk}
\begin{Sinput}
test()
\end{Sinput}
\end{Schunk}
... and all the comments are lost.

running Sweave from Windows XP Explorer
I'd like to create a suitable batch file or shortcut so that I can run Sweave on a .Rnw or .Rtex
file simply by clicking on the file from Windows Explorer in Windows XP (as I do with latex,
bibtex etc). This looks tantalisingly possible using R CMD BATCH or Rterm possibly in combination
with a .bat file. Has anyone succeeded is setting it up and would give me a pointer?
Thanks
