[NTG-context] Can anyone connect context to R or python?
Hi All, I am very interested in creating pdf documents using Context with calculations done in R or Python and then added into the document. If you were using traditional latex this could be accomplished through R markdown or Sweave- is there any way to connect these to Context?

Re: [NTG-context] Can anyone connect context to R or python?
Thank you for all the answers so far !
Ive gathered from that I need to use filter to call R externally.
What I am still most interested in is how I could get a single value from R to
be part of the Context code. (Like you would do with \Sexpr{} in sweave. The
use case for this is that I have some complicated tikz code that makes a fancy
matrix - I want to fill it in with numbers that r reads from a csv file and
processes.

Re: [NTG-context] Can anyone connect context to R or python?
Again thank you everyone for their incredibly helpful advice and
responsiveness!
The work flow I am envisioning is:
1) Use R to read in a csv file, filter according to some rules and then use
propensity score matching (based on r packages) to create a model.
2) The final data output is a table with standardize coefficients and mean
values.
3) This final data output is then used to create a table using Context/ Tikz to
create the very specific format that I need for the final report.
I can do this using Sweave, but I need to be able to use context for some
additional features (in particular the tagging/back end structure).
Best,
Claire

I also just got an incredibly helpful answer over on stack overflow : https://tex.stackexchange.com/questions/453868/how-can-i-use-context-and-r-together Which shows how to use Lua and filter together Claire On 10/6/18, 1:06 PM, "ntg-context on behalf of Aditya Mahajan" wrote: >On Sat, 6 Oct 2018, Kelley, Claire wrote: > >> Again thank you everyone for their incredibly helpful advice and >> responsiveness! >> >> The work flow I am envisioning is: >> >> 1) Use R to read in a csv file, filter according to some rules and then use >> propensity score matching (based on r packages) to create a model. >> 2) The final data output is a table with standardize coefficients and mean >> values. >> 3) This final data output is then used to create a table using Context/ Tikz >> to create the very specific format that I need for the final report. > >Is the final post-processed data a table that can be saved to a CSV file? >If so, the simplest solution will be to write R code (inside a \startR ... >\stopR environment) that does the post-processing and saves the data as a >CSV file. > >Both ConTeXt and TikZ can easily read CSV table and format as desired. > >--- > >I also want to take this opportunity to express my views on intefacing >with external programs.

[NTG-context] External Figure add caption or alternative text for tagged pdf/x
Hi All. I am trying to embed an image in a pdf so that when you open the pdf in acrobat or another reader the image is correctly tagged as an image and there is alternative text. So far I am able to export the back end tags so that I can see tags on tables and paragraphs, but the image comes through tagged as a paragraph and I am unable to add any alternative text. This is the code I am using: \setupbackend [format=PDF/X-1a:2001, export=yes] \externalfigure[district.pdf][height=10cm] Does anyone have any idea how I could fix this? Thanks!
