Programmatically insert text, headers and lists with R markdown

Question

When using R markdown if one wants to add text using code there are some simple ways to do it.

This is also true for tables, using the kable command is

Answer 1

You need to construct your wanted markdown in R and use that together with the argument results = 'asis' in your chunk options. Hence, something like the following will do what you want:

```{r, results='asis'}
headers <- list("We","are","your","friends")
for (i in headers){
  cat("#", i, "\n")
}
```

The for-loop here will create the output

# We 
# are 
# your 
# friends 

which is used directly as input in the .md document.
