Issue connecting to snowflake via dplyr.jdbc.classpath (R - dplyr - jdbc )

I'm fairly confident this is something I'm doing wrong and this probably isn't a bug, but....

I'm running on AWS Linux, trying to connect to snowflake via R/dplyr and having trouble (JDBC driver not able to connect to Snowflake. Error code: 390100, Message: Incorrect username or password was specified..)

Yet, I can use the same info in jdbc/rjdbc in the following and it works (direct connect, no dplyr, just jdbc), ideas? Note I've not included actual passwords/usernames/etc. here...

--works

if (!require("RJDBC")) {
 install.packages("RJDBC",repos="http://cran.rstudio.com/")
 library("RJDBC")
 }
jdbcDriver <- JDBC(driverClass="com.snowflake.client.jdbc.SnowflakeDriver", classPath="~/jdbc/snowflake-jdbc-3.1.1.jar")
 jdbcConnection <- dbConnect(jdbcDriver, "jdbc:snowflake://xxxxx.us-east-1.snowflakecomputing.com", "userID","Password")
 result <- dbGetQuery(jdbcConnection, "select current_timestamp() as now")
 print(result)
 dbDisconnect(jdbcConnection)

> print(result)
              NOW

--disclaimer: my password has a special character in it, does that matter?
