This report benchmark the performance of <%=fcnname%>() against alternative methods.
## Alternative methods
* N/A
<% for (mode in c("integer", "double")) { %>
## Data type "<%=mode%>"
### Data
```r
<%=withCapture({
<%@include file="R/random-vectors.R"%>
data <- rvectors(mode=mode)
data <- data[1:4]
})%>
```
### Results
<% for (ii in seq_along(data)) { %>
<%
dataLabel <- names(data)[ii]
mprintf("%s: %s\n", mode, dataLabel)
x <- data[[dataLabel]]
gc()
%>
### <%=dataLabel%> vector
#### All elements
```r
<%=withCapture({
x <- data[[.dataLabel.]]
stats <- microbenchmark(
"varDiff" = varDiff(x),
"var" = var(x),
"diff" = diff(x),
unit = "ms"
)
})%>
