This report benchmark the performance of <%=fcnname%>() against alternative methods.
|
|
|
|
## Alternative methods
|
|
|
|
* anyNA()
|
|
* any() + is.na()
|
|
|
|
as below
|
|
|
|
```r
|
|
<%=withCapture({
|
|
any_is.na <- function(x) {
|
|
any(is.na(x))
|
|
}
|
|
})%>
|
|
```
|
|
|
|
<% 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 <- names(data)[ii]
|
|
mprintf("%s: %s\n", mode, dataLabel)
|
|
%>
|

### <%=dataLabel%> vector
|
|
|
|
```r
|
|
<%=withCapture({
