[Bioc-devel] class declaration

[Laurent Gautier]

It can certainly be strongly discouraged, just like variable names
should make sense is encouraged.
The R documentation does not seem to make a special case of it
help("'") will tell more about it.

Out of curiosity, I checked and there does not seem to be default
starting packages with spaces in variable names

unlist(lapply(loadedNamespaces(),
                    function(x) grep(" ", ls(getNamespace(x)))))
returns integer(0) here.

There is more to that than spaces, and the following might give
an idea of what is possible (don't try that at home ;-))

> assign("+", function(x, y) 42)
> 2+3
[1] 42
