How to connect R to Clickhouse?

Question

I am new to Clickhouse and am experiencing difficulties connecting R to Clickhouse.

con <- DBI::dbConnect(RClickhouse::clickhouse(),host="srv-clickhouse",username="user",
                      password="pw")

This returns the error

Error in connect(config[["host"]], strtoi(config[["port"]]), config[["db"]],  : 
  DB::Exception: default: Authentication failed: password is incorrect or there is no user with such name

There definitely has to be a user by that name and password which leads me to believe that I've done something wrong while at the same time I'm not sure what I have to put into the host part of the address, nor the port nor in the beginning. Should I add the full URL to the host part? Right now I'm using RClickhouse but my database uses the port 8123. Is there any kind of proper documentation and how to solve this issue?

Thanks
