I wasn't able to install r2nparray using R version 3.0.2. It appears to be due to the missing NAMESPACE file. This is easily fixed as discussed here:
The relevant part is to run this shell command in the r2nparray directory:
echo 'exportPattern( "." )' > NAMESPACE
I will try to submit a PR for this but I'm having troubles with git now.
Thanks, I have this fixed locally, but never made a PR. A PR would be nice.
BLD: New R versions require NAMESPACE file. Closes #1497.
