do.tbl_sql: Perform arbitrary computation on remote backend

In tidyverse/dbplyr: A 'dplyr' Back End for Databases

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.
