Write a Named List of Data Frames to a SQLite Database

Usage

# S3 method for class 'list'
rws_write(
  x,
  exists = TRUE,
  delete = FALSE,
  replace = FALSE,
  meta = TRUE,
  log = TRUE,
  commit = TRUE,
  strict = TRUE,
  x_name = substitute(x),
  silent = getOption("rws.silent", FALSE),
  conn,
  all = TRUE,
  unique = TRUE,
  ...
)

Arguments

x

A named list of data frames.

exists

A flag specifying whether the table(s) must already exist.

delete

A flag specifying whether to delete existing rows before inserting data. If meta = TRUE the meta data is deleted.

replace

A flag specifying whether to replace any existing rows whose inclusion would violate unique or primary key constraints.

meta

A flag specifying whether to preserve meta data.

log

A flag specifying whether to log the table operations.

commit

A flag specifying whether to commit the operations (calling with commit = FALSE can be useful for checking data).

strict

A flag specifying whether to error if x has extraneous columns or if exists = TRUE extraneous data frames.

x_name

A string of the name of the object.

silent

A flag specifying whether to suppress messages and warnings.

conn

A SQLiteConnection to a database.

all

A flag specifying whether all the existing tables in the data base must be represented.

unique

A flag specifying whether each table must represented by no more than one data frame.
