[R] Cannot load irr package

[Rick Bilonick]

The irr package seems to install correctly:

The downloaded packages are in
        /tmp/RtmpsZJJ1h/downloaded_packages



But it won't load. Any ideas?

> library(irr)
Error in parse(n = -1, file = file) : invalid multibyte character in

Error: unable to load R code in package 'irr'


Thanks.
