Copy tables to same source, if necessary

Copy tables to same source, if necessary

auto_copy(x, y, copy = FALSE, ...)

Arguments

x, y	y will be copied to x, if necessary.
copy	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.
