Connecting PostgreSQL with R

问题

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?

回答1:

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

gives me the same error but loading RPostgreSQL

library("RPostgreSQL") 

before making the connection solves it.

回答2:

Package Issue

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

When you use this code you must include the library that uses the driver package so it wont give you an error please use this code and i am sure it will work

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

and that will solve your issue
