This report benchmark the performance of <%=colname%>() and <%=rowname%>() against alternative methods.
|
|
|
|
## Alternative methods
|
|
|
|
* <%=colname%>()/<%=rowname%>() using method="expSumLog"
|
|
* apply() + prod()
|
|
* apply() + product()
|
|
|
|
|
|
## Data
|
|
```r
|
|
<%=withCapture({
|
|
<%@include file="R/random-matrices.R"%>

|
data <- rmatrices(mode = "double")
|
|
})%>
|

```

## Results
