Setup Global Options of RMySQL to use with sqldf in R

I am having a lot of problems with the coding of columns using sqldf and Rpostgree (when I do querys in datasets that contain letters of the Spanish language it converts them into strange characters), for this reason I want to move to MYSQL, but I find its documentation too confusing To use it with sqldf, I need to know how I can enter the parameters of my database to use sqldf with my previously configured database.

Example for Postgree:

options (sqldf.RPostgreSQL.user = "postgres", sqldf.RPostgreSQL.password = "test", sqldf.RPostgreSQL.dbname = "postgres", sqldf.RPostgreSQL.host = "localhost", sqldf.RPostgreSQL.port = 5432)

Someone knows how I can check the options of a specific package, in this case RMySQL.
