pandoc error when handling fraction

[cardiomoon]

Hello !

Package "ftExtra" is very cool. Thanks.

I have a problem to insert fraction in flextable.

Here is reproducible example.

Best regards,

Keon-Woong Moon

library(flextable)
library(ftExtra)
data.frame(math = "$\\frac{1}{2}$",
           stringsAsFactors = FALSE) %>%
  as_flextable() %>%
  colformat_md() 

pandoc: pandoc: createProcess: runInteractiveProcess: exec: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 1

I have sample problem when execute simple latex example.

library(flextable)
library(ftExtra)
data.frame(math = "$e^{i}$",
           stringsAsFactors = FALSE) %>%
  as_flextable() %>%
  colformat_md() 

pandoc: pandoc: createProcess: runInteractiveProcess: exec: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 1

Thank you for using ftExtra. I'm so glad!!

Unfortunately, I cannot reproduce the issue.
Also, even without the issue, faction cannot be rendered by current implementation (cf. https://ftextra.atusy.net/articles/format_columns.html#math for the reason).
I have an idea to make it happen (#70).

colformat_md renders math by a math2html function in a Lua filter.
This function internally calls pandoc again.
This means pandoc executable must be found correctly with a following code.

ftExtra/R/pandoc.R

Line 18 in 4c1a7d4

meta("pandoc_path", rmarkdown::pandoc_exec()),

Would you try what returns by rmarkdown::pandoc_exec()?
