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
<%=withCapture({
<%@include file="R/random-matrices.R"%>
data <- rmatrices(mode = mode)
})%>
```
### Results
<% for (dataLabel in names(data)) { %>
<% mprintf("%s: %s\n", mode, dataLabel) %>
#### <%=dataLabel%> <%=mode%> matrix
