Test cases for Rnw to Rmd conversion

[hturner]

A good test case might be system.file("doc/Comparisons.Rnw", package = "Matrix"). This has no figures, only code chunks and moderately complex LaTeX (e.g. mathematics and a bibliography, but no tables). It looks the Sweave chunks are straight-forward (e.g. no nested chunks), but there are a few attributes (echo/eval arguments to the chunks).

This is also a case that breaks Rnw2Rmd::Rnw2Rmd(), because one of the code chunks has the line

dput(unname(lm.fit(m, yo)$coefficients))

-- the $ is interpreted as the opening fence of an inline code block rather than a verbatim dollar sign, so an error is thrown because there is no matching end fence. If you fix this manually by replacing $ with \$ in the input file, Rnw2Rmd::Rnw2Rmd() runs but many of the code chunks are not converted, because there is not whitespace around them as expected. It also ignores code after % because it is treated as a comment.

So if we can get a workflow working on this case, we would have already have made a big improvement on the state of the art.

I think texor can convert this example almost perfectly now.

Try with following commands:

library(devtools)
setwd("path/to/fzyxh/texor")
load_all()
setwd("path/to/texor-playground/matrix_comparisons")
input_file <- "path/to/texor-playground/matrix_comparisons/Comparisons.Rnw"
rnw_to_rmd(input_file, clean_up = TRUE)
