I'm trying to get Emacs, ESS and Rmarkdown to work together for the first time. Therefore, the problem might be me, and not the software.
I have this program as Prob_11.Rmd:
---
title: "Problem 11, Page 414"
author: "Kevin"
date: "13 Apr 2023"
output: html_document

### Load the sample data ###
Loading the sample data table into two vectors:
``` {r}
(age11 <- c(18, 10, 3, 15, 12, 14, 15, 4, 20, 8))
(age16 <- c(6, 7, 14, 5, 14, 12, 3, 9, 4, 7))
```
I get this as output after choosing Markdown->Preview & Export->Compile:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<p>Loading the sample data table into two vectors:</p>
<pre class="{r}"><code>
(age11 <- c(18, 10, 3, 15, 12, 14, 15, 4, 20, 8))
(age16 <- c(6, 7, 14, 5, 14, 12, 3, 9, 4, 7))
</code></pre>
</body>
</html>
This looks correct, except that I was expecting the last two lines to look like:
> (age11 <- c(18, 10, 3, 15, 12, 14, 15, 4, 20, 8))
[1] 18 10 3 15 12 14 15 4 20 8
> (age16 <- c(6, 7, 14, 5, 14, 12, 3, 9, 4, 7))
[1] 6 7 14 5 14 12 3 9 4 7
Am I doing something wrong? Am I misunderstanding what RMarkdown is doing? I tried options like 'echo=TRUE' and 'eval=TRUE' without success.
Thanks to Dirk Eddelbuettel's suggestion of his render.r executable, I was able to boil it down to the commands I need to render the Rmarkdown.
I run this once in the R console window of Emacs running ESS:
Then, everytime I want to update the document I'm working on, I run:
For me, that outputs an HTML document, that I view in my browser.
I feel certain that there's a better, easier way to do this, in the Emacs/ESS/poly-R/Rmarkdown system, but this is what I needed to get me unstuck, and until I have some time to spare, this is as far as I'm taking it.
