This report benchmark the performance of <%=fcnname%>() against alternative methods.

## Alternative methods

* stats::weighted.mean()
* stats:::weighted.mean.default()


<% for (mode in c("integer", "double")) { %>

## Data type "<%=mode%>"
### Data
```r
<%=withCapture({
<%@include file="R/random-vectors.R"%>
data <- rvectors(mode = mode)

```

## Results

<% for (ii in seq_along(data)) { %>
<%

### <%=dataLabel%> vector

```r
