do.tbl_sql: Perform arbitrary computation on remote backend
In dbplyr: A 'dplyr' Back End for Databases
do.tbl_sql R Documentation
Perform arbitrary computation on remote backend
Description
Perform arbitrary computation on remote backend
Usage
## S3 method for class 'tbl_sql'
do(.data, ..., .chunk_size = 10000L)
Arguments
.data
a tbl
...
Expressions to apply to each group. If named, results will be
stored in a new column. If unnamed, must return a data frame. You can
use . to refer to the current group. You can not mix named and
unnamed arguments.
.chunk_size
The size of each chunk to pull into R. If this number is
too big, the process will be slow because R has to allocate and free a lot
of memory. If it's too small, it will be slow, because of the overhead of
talking to the database.
