    - !expr system.file("includes/stylesheets/summarytools.css", package = "summarytools")

# Prerequisite

```r
devtools::install_github('dcomtois/summarytools', ref = 'dev-current')
```

# Setup

```{r setup, include=TRUE}
library(knitr)
opts_chunk$set(comment=NA, prompt=FALSE, cache=FALSE, results = 'asis')

library(summarytools)
st_options('footnote', NA)
st_options('plain.ascii', FALSE)
```

## The problem

Those sneaky `[[n]]` indices...
```{r groupstats_html}
groupstats <- by(data = exams, INDICES = exams$gender, FUN = descr, stats = c("mean", "sd", "min", "med", "max"))
view(groupstats, method = 'render')
```

This gives similar results:
```r
lapply(groupstats, print, method = 'render')
```

## Markdown rendering is fine using view() function
```{r groupstats_md}
view(groupstats, method = 'pander')
```
