Having multiple pander()s in a function

Question

How do I create multiple outputs via pander() in a knitted document "asis" ?

When I have multiple calls of pander in a function, only the most recent one is shown in the HTML output. Here's an example:

tmp = function() {
  pander('A')
  pander('B')
  pander('C')
}
tmp()

In the knitted document this gives: C

I could set panderOptions('knitr.auto.asis', FALSE) or I could use cat() so that the pander() output is written to the standard output. But then it's formatted as code, not as part of the document. As I need pander() to format a few tables for me, this does not help.

The tmp function will return only the last object -- that's why only C is printed. If you want to write each object to the stdout right away without the auto-asis convenience option, then you have to both disable the option like you did and use the relate knitr chunk option, eg:

```{r results='asis'}
library(pander)
panderOptions('knitr.auto.asis', FALSE)
tmp = function() {
  pander('A')
  pander('B')
  pander('C')
}
tmp()
```

See more examples in the related "Using pander with knitr" vignette.

Ah, great! the `results='asis'` option was what I was missing! — BurninLeo, Feb 25 '17 at 19:22
