 Any access to WMS and WFS would probably be best done using GDAL and
OGR via the rgdal package.... Let's see...

 GDAL has a WMS driver, but it seems you do have to create a 'local
service description' file. www.gdal.org seems down at the moment, so
here's a google cache link:

 For WFS, there's some recent discussion on the gdal-dev list:

 so it might be coming soon. Can you wait?

 To do WFS from scratch in R is probably going to need XML parsing,
and then it'll probably also need OGR too unless you want to hand-code
understanding the returned GML...
