Set dittodb's debug levelSource:
It can be helpful to see what's going on by increasing dittodb's verbosity
which will show what's going on under the hood (e.g. what queries are being
requested, from where). This sets the option
dittodb.debug to the value
given in the
level argument. The option can be set directly with
options(dittodb.debug = n) as well.
level argument is a numeric, where 0 is the default and (relatively)
silent. The higher the level, the more verbose dittodb will be.
Currently, dittodb only has one level of debugging (any value 1 or greater), but more might be used in the future.
