Hi,
Following a question about the broken R module (R the statistical software),
Aditya suggested me the filter module (thanks to him). I’m about to distribute
a set of course notes to colleagues, and I need to deal with details now. I
have one problem and two questions.
1) the filter collect R code between \startR / \stopR and submit this code to
R. As it can be seen in the following minimal example, when a label contains an
accented character (« Fréquence » in my example), the pdf graphic does not
contains the « é ». Strangely, the snippet of code (which is saved locally as «
test2-temp-R-0.tmp » (for test2.tex)) when submitted with the same command as
the filtercommand, works correctly; that means the same file works when
submitted to R outside of ConTeXt. I have no idea how to solve this.
Are you running the exact same command as the `filtercommand`. If so, I don't know why
running the `filtercommand` through context vs directly typing it on the terminal should
behave differently. The filter module effectively just runs
os.execute("filtercommand"). I don't use R so I am unable to debug further.
2) In a teaching context, we may want sometimes to show the code. The filter
module actually permits to show the output of the code submitted to R (which
can include or not the input commands); would it be possible to typeset the
submitted code ?
This is an adapted version of the code that I use for my course where I use the
vim module to do the typesetting:
\usemodule[filter]
\usemodule[vim]
\definecolor [darkblue] [r=0.1, g=0.11, b=0.84]
\definecolor [darkgreen] [g=0.7]
\definecolor [lightblue] [h=87cefa]

\externalfilterinputfile\space \externalfilteroutputfile},
output=\externalfilterbasefile.out,
directory=output,
readcommand=\ShowOutput,
read=no,
cache=yes,
purge=yes, % THE COMMA WAS MISSING
]
\starttext
Some text...
\startR[read=yes]
pdf("RPlots/MyHistogram.pdf",5,5)
X <- rnorm(200,mean=10,sd=2)
hist(X, col = "red3" , xlab="Score QI" , main="", ylab="fréquence")
\stopR
\externalfigure[RPlots/MyHistogram.pdf][width=.5\textwidth]
\stoptext
3) Finally, using "R CMD BATCH… » as the filtercommand add an extra line at the
end of the output file which can be typeset to visualize results. Would it be
possible by a magic trick to deleter the last line of the file ?
It is possible to filter lines using `\typefile[range={start,
stop}]{filename}`. You can use `range={1,3}` to only include lines 1 upto 3 or
`range={1, +2}` to include line 1 followed by 2 lines. What you want is
something like `range={1,-1}`, i.e., include from the first to last-1 line, but
this is not currently supported. You could ask Hans to do so, as it is
relatively simple to add. Of course, you will then need to document this on the
wiki.

[NTG-context] using annotations for extended print handling
Dear list,
I have an over a thousand pages document generated with ConTeXt.
I need to print and chapters and part of chapters (or send to other people).
/PrintPageRange is great (and you can even generate a new document
containing only the pages in /PrintPageRange). But the issue here is
that I would need to recompile the document again for each new required
/PrintPageRange.
Another approach would be to add PDF annotations (outside page
boundaries) to store the desired information.
So I created text annotations (using \comment) with author information
composed from unit number (such as "i3", "ii9" or "iii28"), info on the
unit part (such as "-explanation", "-synopsis", "-exercises", or others)
and position ("-start" and "-stop").
This would make author fields such as "i3-start" (which has a
corresponding "i3-stop", or "ii22-synopsis-start" (with the
corresponding closing annotation).
To make easier to identify these annotations, they all share the same
title. As contents, all these text annotations have the page number.
From the generated PDF document, I need to read all text annotations in
order to extract two fields from those annotations that contain a
"whatever" /Subj. These fields are /T and /Contents.
I guess that the way to deal with the (over 700) annotations would be to
store both fields in a Lua table. But this is only a suspicion, since I
don’t know how to read the values, how to store them, or how to compare
them with specific units or unit parts to get these page numbers.
I mean, with a command such as
\extractpages{i5,i8-exercises,i15-explanation} would get the pages for
each "-start" and "-stop" that could be passed automatically to a
\filterpages command.
A sample that generates something similar:
\setuppapersize[A8]
\setupinteraction[state=start]
\starttext
\dorecurse{5}{\part{\romannumerals{\recurselevel}}
\dorecurse{15}{\chapter{\recurselevel}
\comment
[title=whatever,
color=yellow,
%~ the following code is to have expansion in interaction
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]].."-start")}}]
{\pagenumber}
\doloopoverlist{explanation,exercises,synopsis}{\chapter{\recurselevel}
%~ I would like to use \recursestring, but it is undefined here
\comment
[title=whatever,
color=green,
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]]..
[[-\recurselevel]].."-start")}}]
{\pagenumber}
\dorecurse{5}{\null\page}
\comment
[title=whatever,
color=blue,
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]]..
[[-\recurselevel]].."-stop")}}]
{\pagenumber}
}
\comment
[title=whatever,
color=red,
author={\ctxlua{context([[\namedstructurevariable{part}{title}%
\namedstructurevariable{chapter}{title}]].."-stop")}}]
{\pagenumber}
}
}
\stoptext
Is there a way to deal with the annotations in the document generated
from the code above, in the way I described before?
Many thanks for your help,
Pablo
