How to Use Spell Check in Rmarkdown

How can I use spell check in Rmarkdown?

Here are three ways to access spell checking in an rMarkdown document in rstudio:

1. A spell check button to the right of the save button (with "ABC" and a check mark).
2. Edit > Check Spelling...
3. The F7 key

A keyboard alternative to option 2 is alt + e + s. That is, while holding down the alt key, type e followed by s.

RStudio does not have an as-you-type spell checker; you'll have to invoke spell checking manually. To do this, go to the Edit menu and choose Check Spelling, or press F7.

Note that spell checking is not performed on code files, only on document files (i.e. you won't get spell checking an .R file, but you will in an .Rmd file).

First go to Tools-> Global options -> Spelling. Then install the dictionary in Spanish and click on apply.

Now you can open a new file in rmarkdown or rsweave. And have an automatic spelling corrector by clicking on ABC. I think it's very useful for the entire Spanish-speaking community that uses Rstudio to make reports.

Remove Hashes in R Output from R Markdown and Knitr

You can include in your chunk options something like

comment=NA # to remove all hashes

or

comment='%' # to use a different character

More help on knitr available from here: http://yihui.name/knitr/options

If you are using R Markdown as you mentioned, your chunk could look like this:

```{r comment=NA}
summary(cars)
```

If you want to change this globally, you can include a chunk in your document:

```{r include=FALSE}
knitr::opts_chunk$set(comment = NA)
```

How to spell check code and markdown within Visual Studio Code?

After testing a few of the extensions I've decided to use Code Spell Checker. It has a super useful shortcut CTRL+. that shows suggestions for spelling.
