Copy tables to same source, if necessary
auto_copy(x, y, copy = FALSE, ...)
y
will be copied to x
, if neccessary.
If x
and y
are not from the same data source,
and copy
is TRUE
, then y
will be copied into the
same src as x
. This allows you to join tables across srcs, but
it is a potentially expensive operation so you must opt into it.
Other arguments passed on to methods.
