[R-pkg-devel] two functions with the same name when importing

[Bernd.Gruber]

@Martin Morgan<mailto:mtmorgan.bioc using gmail.com>

Thanks to your hint if found this:

@rawNamespace import(adegenet, except = plot)

which works beautifully  and no need to go through each Namespace function.

Thanks again to everyone.

RShowDoc("R-exts") setion 1.5.1 Specifying imports and exports indicates that imports() has an except= argument, so

import(adegenet, except = plot)

might do the trick. Use it in your package as `adegenet::plot()`.

Just get a copy of the adegenet NAMESPACE file to get all of its
exports. Edit the list down to the ones you use, and use a text editor
to change the export directives to importFrom directives. It's not
really that hard.

The path to the NAMESPACE file is given by

system.file("NAMESPACE", package="adegenet")
