using R Under development (unstable) (2013-07-02 r63156)
using platform: x86_64-unknown-linux-gnu (64-bit)
checking R code for possible problems ... NOTE
Found an obsolete/platform-specific call in the following function:
‘.openInteractiveDevice’
Found the platform-specific devices:
‘X11’ ‘windows’
dev.new() is the preferred way to open a new device,
in the unlikely event one is needed.
