Directions / Assignment Chunks

[daviddalpiaz]

Currently cannot be used for both r and asis engines.

I think this is wanting to add another flag to processing?

I'm not sure we can easily embed code chunks in directions...

A sample document.

```{asis, directions = TRUE}

Some directions
```{r}
1 + 1  # a line of code

Another paragraph.

Readability wise, this doesn't work out nicely.

[daviddalpiaz]

I'm not sure what that example is showing. I don't see the need to have one chunk inside of another.

[coatless]

The starting issue is a bit sparse. Did you mean something along the lines of:

```{asis, directions = TRUE}
Text

# code

going to:

Text

code

e.g. there is no discrimination between tag placement?

[daviddalpiaz]

Written in lab00-main.Rmd:

```{asis, assign = TRUE}
Text

# your code here

Becomes in lab00-assign.Rmd:

Text

# your code here

[coatless]

So, we can use this to determine the asis chunk:

asis.*?,.*?directions[[:space:]]?=[[:space:]]?[tT]?[rR]?[uU]?[eE]?

And we can force remove in the r chunk with:

,?[[:space:]]?directions[[:space:]]?=[[:space:]]?[tT]?[rR]?[uU]?[eE]?

As of now, can I include R code only in -assign.Rmd but not in -sol.Rmd?

As of now, can I include R code only in -assign.Rmd but not in -sol.Rmd?

If a code chunk is marked by:

• solution = TRUE, only display in *-sol.Rmd.
• directions = TRUE: only display in *-assign.Rmd
• Neither solution = TRUE or directions = TRUE: display in both *-sol.Rmd and *-assign.Rmd

These two keywords are hard-wired at the moment:

@coatless Thanks, but sorry I don't get it here.

What I want to do is

```{r, directions = TRUE}
1+1

which only returns the plain text "1+1".

I want it to generate R code only in `*-assign.Rmd`. Is this currently supported?

[coatless]

@inmybrain unfortunately, no. The directions= option is only supported under asis.

[inmybrain]

@coatless Thanks for the clarification. Is there any possibility to include such an option?

[coatless]

@inmybrain not until the weekend. My mind is on a paper deadline.

[inmybrain]

@coatless Oh I didn't mean to rush you at all. Please take your time and consider including the option when you have time. Wish you finish your paper by the due date.
