This report benchmark the performance of <%=colname%>() and <%=rowname%>() against alternative methods.
|
|
|
|
## Alternative methods
|
|
|
|
* apply() + quantile(..., type = 3L)
|
|
* Biobase::rowQ()
|
|
|
|
<% for (mode in c("integer", "double")) { %>

## Data type "<%=mode%>"

### Data
|
|
```r

```

### Results
