Connecting PostgreSQL with R

Question

I'm trying to make a connection to PostgreSQL database in R.

I'm writing this

drv <- dbDriver("PostgreSQL")

But in result i have an error:

Error: Couldn't find driver PostgreSQL. Looked in:
* global namespace
* in package called PostgreSQL
* in package called RPostgreSQL

What am I doing wrong?

Answer 1

drv <- DBI::dbDriver("PostgreSQL")

gives me the same error but loading RPostgreSQL

library("RPostgreSQL") 

before making the connection solves it.
