You referred to another package that exports an R5 class. Which one?

Thanks for your help.

When I run `R CMD check .` on the source directory of my package I am
told that:
Error: could not find function "Blob"

However, when I install and load the package, I can successfully run
the command in the example.

Does someone know why this is happening?

The relevant definitions and the example (in Rd format):

R5 definition:
```
draw.Blob <- function (type = 'small')
{
'Something about blobs'
type <<- 'small'
}

Blob <- setRefClass (
Class = "Blob",
fields = list(type = 'character'),
methods = list(draw = draw.Blob)
)
```

Example:
```
\examples{
Blob(type = 'small')
}
```

The symptoms make it look as though the *function* Blob is not exported. I see in your source that you do export the *class* Blob, but the docs don't make it clear to me that this also implies export of the generator function.

So I'd add

export(Blob)

to your NAMESPACE. I just checked another package that exports a class, and it separately exported the generator function, so I guess this is known.
