I think I notice that
- a stata chunk with a single display command produces no output
- a stata chunk starting with a blank line followed by a display command produces output as expected
- a stata chunk starting with a display command followed by subsequent display commands omits the output from the first display command.
An example Rmd file is below - pdf output attached stmd-test.pdfhttps://github.com/Hemken/Statamarkdown/files/5621596/stmd-test.pdf
I am not sure where the error is for these, and maybe there are 2 or more little errors.
I tried to investigate
- at the end of stata_engine(), I included a print(knitr::engine_output(options, options$code, out)) and that looks ok to me.
- when I include a print(x) at the beginning of stataoutputhook() there looks to be an issue relating to how character strings are parsed/joined, maybe because the display output includes string quotes.
- I also wondered if there was a second small error for the loss of the single/first line, and was wondering if the firsttext code has a problem because I see the warning
Warning messages:
1: In min(grep("[[:alnum:]]", y)) :
no non-missing arguments to min; returning Inf
I have Stata 15.1 (but don't think this is anything to do with the Stata version).
Sorry I can't propose fixes.
Example Rmd file code
title: "display command output examples"
output: pdf_document
# remotes::install_github("hemken/statamarkdown")
library(Statamarkdown)
library(sessioninfo)
Output for this chunk is missing
display "Hello 1"
Output correctly displayed with the first blank line removed
di "Hello 2"
Output from the first command omitted
di "Hello 3"
di "Hello 4"
Checking if these occur without the use of string quotes in the command
display 1
di 2
di 3
di 4
sessioninfo::session_info()
