Connect with R Language
Configuration
After completing the installation of the R programming environment, you need to perform some configuration steps so that the RJDBC library can connect to and access the TDengine time series database correctly.
- Load the RJDBC library and other necessary libraries in your R script:
library(DBI)
library(rJava)
library(RJDBC)
- Set the JDBC driver path and JDBC URL:
# Set the JDBC driver path (modify it based on where you actually saved it)
driverPath <- "/path/to/taos-jdbcdriver-X.X.X-dist.jar"
# Set the JDBC URL (modify it according to your specific environment)
url <- "<jdbcURL>"
- Load the JDBC driver:
# Load the JDBC driver
drv <- JDBC("com.taosdata.jdbc.rs.RestfulDriver", driverPath)
- Create a connection to the TDengine database:
# Create a database connection
conn <- dbConnect(drv, url)
- Once the connection is successful, you can use the conn object to perform various database operations such as querying data, inserting data, etc.
