Question

I have a large data-set and I will preform some analysis in R software.
While I could not import the data properly to R.

I get this error:

Error in postgresqlNewConnection(drv, ...) : RS-DBI driver: (could not connect User@local on dbname "Intel"

I have used PostgreSQL to open data and somehow manage it. How can I import the existing data in the PostgreSQL to the R software?

Answer 1

drv <- dbDriver("PostgreSQL")
con <- dbConnect(drv, host='localhost', port='5432', dbname='Swiss',
                 user='postgres', password='123456')

Moreover, “RPostgreSQL” package in R should be installed.
