 There is only one core function in upsertR: ```upsert()```, which lets you upsert a dataframe to a target SQL server. See below for an example. 
 
 ```R
-upsert(con,    # SQL server connection string
-       df,     # input dataframe
-       schema, # Target schema name on SQL server
-       table,  # Target table name on SQL server
+upsert(connection = con,    # SQL server connection string
+       dataframe = df,     # input dataframe
+       schema = schema, # Target schema name on SQL server
+       table = table,  # Target table name on SQL server
        delete = TRUE) # specifies whether to delete old ID's not present in input DF. TRUE deletes old ID's
