#Get the corresponding grid cells for each earthquake epicenter (lat-long pair) dgquakes$cell <- dgtransform(dggs,dgquakes$lat,dgquakes$lon)

Thanks for letting me know.

For now, I've updated the dgtransform message to include a warning that notes the swapped order of arguments. I'll rebuild the examples later.

I think this is fixed in the new version on CRAN.
