parsing pdf files
I have a pdf file that I would like to parse into R:
http://www.williams.edu/Registrar/geninfo/faculty.pdf
For now, I open the file in Acrobat by hand, then save it "as text"
and then use readLines(). That works fine but a) I am concerned that
some information may be lost and b) I may be doing this a lot, so I
would rather have R grab the information from the pdf file directly.
So: is

Reading PDF files
Hi:
I need to do text mining on PDF files. I understand there is a readPDF
command in tm that can be used. Have read the 2008 posts on converting
PDF files to text by Tony Breyal and others.
Wondering if the procedure has been standardized in any tutorial or
otherwise? Being new to R, I was able to follow only part of the
discussion.
Any way to get a set of step by step instructions

Bug in Acrobat Reader 7 (or R?) with translucent text
My setup: R 2.4.0, Windows 2000, Acrobat Reader 7.
When I create a .pdf with translucent colors, the translucency works
correctly for points, but not for text. Below is some R code that
creates a .pdf with this phenomenon.
I was going to report this as a bug in R, but then I tried to view the
pdf with a couple of other viewers and found that at least one of the
viewers correctly displayed the

readPDF() -- unsure how to install xpdf to make this work?
Dear R-Help,
I need to convert a set of '.pdf' files into an equivalent set of
'.txt' files. This is so that i can do some text mining on the
content.
In the latest R-News letter (http://cran.r-project.org/doc/Rnews/
Rnews_2008-2.pdf), the package 'tm' for text mining is mentioned. In
that lovely package, there is a function called 'readPDF()'. In order

Parsers for input to index?
The documents we want to index come in many formats; e.g., HTML, PDF,
RTF, Word, Excel, etc., etc., etc. I''ve been searching to find parsers
that will translate each of these formats to indexable text, but have
had little success. Any help will be appreciated.

several postscript problems
Hello everyone,
I'm currently trying to export a couple of graphs to pdf . Postscript
would be fine too, but I'm using odd page dimensions, which seem to be
overwritten when using the "ps2pdf" command. I'm using the pdfpages
package in LaTeX to put 6 graphs onto one page (this is why it ought to
be a pdf in the end).
I have two problems:

Evaluating R expressions from C
I am currently puzzled by a passage in the R Extensions manual, section 5.10:
SEXP lapply(SEXP list, SEXP expr, SEXP rho)
{
R_len_t i, n = length(list);
SEXP ans;
if(!isNewList(list)) error("`list' must be a list");
if(!isEnvironment(rho)) error("`rho' should be an environment");
PROTECT(ans = allocVector(VECSXP, n));

White lines on persp plots in pdf format
Hi,
I am using the persp function to plot 3D surfaces, but the plots have
"little white lines" when I print them to a pdf file (visible in
Acrobat, Foxit, Evince, Xpdf and Gimp). This does not happen when I
create png or tiff images. Here is some sample code:
pdf("test.pdf")
x <- seq(0,1,length=101)
f <- dnorm(x, 0, 0.25)
z <- c()
for(i in 1:100) z <-

evince not showing "greek" and "math" in *.pdf plots
Hi
I don't think this is an R issue (it is separate from the Cairo Symbol
font problem).
For PDF output, R actually relies on the Symbol font having the Adobe
Symbol Encoding (Appendix D of the PDF Reference
https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/pdfreference1.7old.pdf)
and just outputs the font as "Symbol", which relies on it being one of

Embedding R's math expressions fonts for graphics generated by pdf() and postscript()
Dear list,
First, I am not writing to ask about embedding Computer Modern font in
graphics produced by R.
I am generating plots to be saved using pdf() and postscript() in R,
and I make use of some math expressions that are provided by R,
namely, some greek letters. My question is, do I need to embed the
fonts that include these math symbols (say, if they are going out for
publication, to have

evince not showing "greek" and "math" in *.pdf plots
I see. Peter, you are right about the font that causes the issue. Paul,
thanks for your insights. I'll bring this to the Fedora font experts to see
if we can arrive at a more permanent fix. I'll report back with any
conclusion.
@Martin: Meanwhile, at least you have options. One is to embed the fonts,
either as Peter suggested or using cairo_pdf instead. Alternatively, Peter

evince not showing "greek" and "math" in *.pdf plots
Martin, I wouldn't rule out an R issue yet. Fonts are... tricky. So I'm
cc'ing Paul Murrell here.
I tried several viewers here and I see the following: Chrome, Firefox and
Libreoffice Draw show the symbols; however, evince, okular and xournal++
agree on **not** showing the symbols. **If** there is a bug, the bug would
be in fontconfig, because these ones AFAIK properly delegate on

Shaping traffic on heavily oversubscribed links?
Hi all,
I am having some fun with traffic shaping, and have run into an
interesting situation. Here is South Africa, most internet links are
heavily oversubscribed, which means that in most cases the local link is
_not_ the bottleneck, and shaping on the local link does not help that
much...
Does anybody have some tips on shaping such links? How can you get
interractive traffic if you

acrobat reader for x86_64?
Adobe doesn't seem to have acroread for x86_64 linux, or at least I don't
see it anywhere.
Anybody know otherwise?
Evince and other tools work pretty well, but I have always liked having
the "real thing" around for those occasions when they don't.

What is acceptable network latency for voipconnection?
That "program" will be detected by your ISP within a day or so,
determined to be a virus, and your service will get disconnected...which
n turn will not help your latency or jitter at all.
VoIP can tolerate a fair amount of latency; latency over about 100ms is
heard as a perceptible delay resulting in a connection that appears to
be half duplex.
Jitter, on the other had, is the real
