Can you connect R to SQL?

If you are a customer of RStudio, we recommend using the RStudio Professional Drivers, which are easy to install and designed to work with our products. Then, when it comes to the connection from R to the database, we recommend using the odbc package, which is a DBI compliant interface to using ODBC drivers.

What is ODBC in R?

The odbc package provides a DBI-compliant interface to Open Database Connectivity (ODBC) drivers. It allows for an efficient, easy way to setup connection to any database using an ODBC driver, including SQL Server, Oracle, MySQL, PostgreSQL, SQLite and others. The implementation builds on the nanodbc C++ library.

How do I connect to ODBC database in R?

Connect to a Database

  1. Install the DBI and odbc package: install.packages(“DBI”) install.packages(“odbc”)
  2. Verify that odbc recognizes the installed drivers using odbcListDrivers() .
  3. Determine if a DSN is going to be used to connect to the database.

How do I use DBI in an R package?

R scripts and packages use DBI to access various databases through their DBI backends. The interface defines a small set of classes and methods similar in spirit to Perl’s DBI, Java’s JDBC, Python’s DB-API, and Microsoft’s ODBC. It supports the following operations: Most users who want to access a database do not need to install DBI directly.

What do you like most about R user interface?

3) User Interface makes it easy to read R code generated, and commit code. 4) For repeatable analysis-like reports or creating models it is very useful as you can replace just one widget and other widget/operations remain the same. 5) Very easy to zoom into data points by double clicking on graphs. Also to change colors and other options in graphs.
