control table and figure seq_id from yaml header or chunk options

[zilch42]

The issue I am experiencing is that officedown uses different field code SEQ ids for tables and figures than word so if I create a word document with officedown and then make a few table or figure additions manually, they end up belonging to different sequences. This may be a locale thing, I'm not sure. I am using an Australian version of Word.

manually generated in word:
{ SEQ Table * ARABIC }
{ SEQ Figure * ARABIC }

generated by officedown
{SEQ tab * Arabic}
{SEQ fig * Arabic}

I understand the officer has some control over this with run_autonum(seq_id = "fig") but I don't call that directly when using officedown: e.g:

```{r tab.cap='iris', tab.id='iris'}
head(iris)
```

Would it be possible to have options either in the yaml header or chunk options (so that global defaults could be set) for defining which seq_id is used? If this is a locale based issue then it would allow users to define the correct ID for their localized version of word.

E.g.

officedown::rdocx_document:
  base_format: "bookdown::word_document2"
  reference_docx: "template.docx"
  number_sections: FALSE
  tables:
    style: Table_CSIRO
    caption: 
      style: Caption
      pre: 'Table '
      sep: ' '
      seq_id: Table
    conditional:
      first_row: true
      first_column: true
      last_row: false
      last_column: false
      no_hband: false
      no_vband: true
  plots:
    style: 'Body Text'
    caption: 
      style: Caption
      pre: 'Figure '
      sep: ' '
      seq_id: Figure

If there is already a way of doing this, please forgive me. I have looked everywhere for it.

Yes, it's a local thing. In France, it's "Table" for example and this is stored in a hidden Word template somewhere in your computer.

You can use knitr chunk option fig.lp (See https://yihui.org/knitr/options/) and officedown is supporting via officer option tab.lp which does not exist with knitr (to my knowledge)

Thanks David! that's great to know. I've now got fig.lp working, but I think I found an issue with tab.lp when used in conjunction with flextable. If you knit the following example and look at the field codes generated, the first one uses { SEQ Table * ARABIC } as set in the global chunk options, but the second one which is a flextable uses {SEQ tab * Arabic}

bookdown::markdown_document2:
  base_format: officedown::rdocx_document
  reference_docx: "template.docx"

```{r include=FALSE, warning=FALSE, message=FALSE}
# load libraries
library(knitr)
library(officedown)
library(officer)
library(flextable)
library(tidyverse)

# global chunk options
knitr::opts_chunk$set(fig.lp = "Figure", tab.lp = "Table")
```

This is \@ref(tab:mtcars)

```{r tab.cap='MT Cars', tab.id='mtcars'}
mtcars %>% head(6)
```

This is flextable \@ref(tab:mtcarsflex)

```{r tab.cap='MT Cars', tab.id='mtcarsflex'}
mtcars %>% head(6) %>% flextable()
```

flextable 0.6.6
officedown 0.2.3.001
officer 0.3.18
R 4.0.5

I don't think the example you provided is valid. I did not run it, I am sure it will produce an HTML file.

I will investigate that later then.

Note tab.lp is not documented as it was not supposed to be used by users. Now I need to go fix an issue with flextable because you want to change it ;)
