I am having trouble connecting to my Amazon RDS PostgreSQL database using R on RStudio and using the package RPostgreSQL.

I am running:

library("RPostgreSQL")

drv <- dbDriver("PostgreSQL")
con <- dbConnect(drv, dbname="mydbname", 
                 host="........us-west-2.rds.amazonaws.com", port=5432, 
                 user="myuser", password="mypassword")

After running this line, I get the error:

Error in postgresqlNewConnection(drv, ...) : RS-DBI driver: (could not connect myuser@.........us-west-2.rds.amazonaws.com on dbname "mydbname" )

Note that I have the correct dbname, host, port, user and password because I am able to connect to the Amazon database using pgAdmin3

Here is my session info:
