In knitr, no output from pander in for loop

Question

Using knitr in RStudio, pander does not produce any (or correct) html output when in a for loop. Here is a minimal case, as an Rmd input file.

Answer 1

@daroczig answered in the comments :

1. change knitr chunk option results to asis, either at the global level knitr::opts_chunk$set(results="asis") or at the chunk level ```{r,results="asis"}
2. disable panderOption knitr.auto.asis : panderOptions('knitr.auto.asis', FALSE)

Testing **when** pander doesn't work in for loop

```{r global_options, include=FALSE}
knitr::opts_chunk$set(fig.width=7, fig.height=5, echo=TRUE, warning=FALSE,
  message=FALSE)

```

```{r,results="asis"}
library(pander)
panderOptions('knitr.auto.asis', FALSE)

r <- 1:10

for (i in 1:2) pander(summary(r))

```
