I have a simple LaTex code in my R notebook as
$y=\frac{(x-\mu)}{(max-min)}$
When I hover on the code, I see the output and also when I knit to HTML. However, how do I see the rendered output within the .RMD file?
I know this can be done because once I accidentally hit something on the keyboard and I was able to see the rendered LaTeX output within the .RMD file itself. I just do not know what I hit and I am not able to reproduce that behavior. I was not able to find in documentation as well.
Display equations (surrounded with $$) preview as a chunk result rather than a popup, as inline equations ($) do.
$$y=\frac{(x-\mu)}{(max-min)}$$
However, note that $$ will print the math in its own paragraph/div while $ produces inline output. AFAIK, there is no way to have inline equations preview without hovering over them.

I have been writing a document in bookdown where within the *.Rmd file I call a figure by using the following syntax
\#ref(fig:MyFigureName)
This differs slightly from the notation that you would use in a normal RMarkdown file exporting to latex which would be
\ref{fig:MyFigureName}
The issue I am running into is that when I write something in bookdown the function calling the Figure is not being highlighted properly (see image below).
I have imported my own rsTheme (which is from my understanding, basically a .css file) but I don't see an option to add keywords to highlight.
But I would like for the entire function to be colored differently from the inline text (Photoshop version of desired output shown below)
Does anyone know how I would edit my *rsTheme file in order to accomplish this?
Thanks!
I recently updated my RStudio and while writing an R Markdown document in the Source Window, whenever I run a code in a chunk of the RMD, the output is shown in the source window itself in the following manner. It gets too messy when there are huge plots. Would like to disable this feature if possible and revert back to good old style of displaying output in the Console/Plot viewer window only.
Output executed and visible below the Chunk in the Source Window
Thanks
Try this in Rstudio.
Tools > Global Options > R Markdown > Uncheck: Show output inline for all R Markdown Documents.
That should disable inline code chunk output when you're editing R Markdown documents.
Does that get you what you're asking?
Looks like OP had his question answered, but if toggling "Show output line for all R Markdown Documents" has no effect, you may be dealing with the bug detailed here: Chunk output in console not always available. You'll have to uncheck that box, restart, and then select the option to "Chunk Output in Console" from the output menu before re-enabling the former setting.
Is there a way to define a command that can be used as a short cut for frequently used text or html commands in knitr when compiling to html?
I use knitr to compile an rmkardown file (.Rmd) and the output is a html file (i.e., I press Knit HTML in RStudio).
To be more specific, let me add an example: I want to separate the percent sign by a hair space from the number before, which I achieve by typing, e.g., 5 %. It would be very convenient, if I could define a command, let's say \perc, that I can use instead, such that 5\perc would be equivalent to 5 %.
Is this at all possible and if yes, how can it be done?
You can define an R function and then call it inline. For example:
```{r}
perc <- function(){
" %"
}
```
This is inline r code 5`r perc()`
I think you could also use it in chunks where the result would be 'asis'.
I have a .Rnw document in which I include childs. The childs produce tables via the 'latex' command of the Hmisc library in R.
When I make changes in the child documents, these changes do not anymore change the pdf document. My first guess was to use the chunk option 'eval=TRUE', but this does not change anything. Then, I saw, that the tables are actually saved to a .tex file with same name as the .Rnw document. I deleted this file and after compilation with knitr I got an error:
Error: Latexmk: Could not find file documentname.tex.
I assume, this is not the way to do it. Now I am out of ideas what to do. I appreciate some help on my problem.

Allright, when trying to construct a simple example, I actually found out, that neither the packages I included nor the nesting of child documents interfere with the compilation via knitr. The reason was a simple error in the low-level .Rnw document, where a Hmisc latex table had a label, that missed a closing speech mark.
This causes then the output pdf not to change - I assume, that in this case the already constructed .tex file is included instead of letting knitr recompile the .Rnw documents and this hasn't changed since the last compilation?
What I wonder about is the different format of the landscape ctable in the document. Using a simple knitr document just with \documentclass{article} produces well placed tables. In my document using a template for the JFE, I get a table that extends over the whole page and even in footnotesize it is far away from the great appearance in the simple document. There is only a margin of less than half a cm on the right and the left. Page size is the same: both US letter... Can I probably control that via knitr or only via resizebox?
I was learning about using the command line version of latex today, and I was experimenting with outputting .tex to .dvi, and then .dvi to .png.
The problem is, I have a simple .tex document which contains some math. The goal is to eventually produce a png form of the equation. But when I run:
$ latex -output-format=dvi test.tex
$ dvipng test.dvi
I get test1.png that is shaped like a regular letter-sized page. I only want an image that is as big as the equation needs to be. I'm sure I'm missing something obvious, but I can't figure it out!
Is there a command line option for either latex or dvipng to specify that the output file should only be set on a page as large as needed to render the equation?
Here's my example test.tex:
\documentclass{article}
\begin{document}
The solution to $\sqrt{x} = 5$ is $x=25$.
\end{document}
Thanks!
Try
dvipng -T tight filename
EDIT: As Mr tur1ing points out, you'll also want \pagestyle{empty} to avoid having a page number muck up the works.
Try mathurl and Roger's Online Equation Editor. There probably several other such sites.
