This report benchmark the performance of <%=colname%>() and <%=rowname%>() against alternative methods.
## Alternative methods
* apply() + rank()
<% 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
```r
<%=withCapture({
X <- data[[.dataLabel.]]
gc()
colStats <- microbenchmark(
colRanks = colRanks(X, na.rm = FALSE),
"apply+rank" = apply(X, MARGIN = 2L, FUN = rank, na.last = "keep", ties.method = "max"),
