The file /library/RMySQL/html/dbEscapeStrings.html documents dbEscapeStrings()
In the example, an 's' is missing in line 3:

## Not run: 
tmp <- sprintf("select * from emp where lname = %s", "O'Reilly")
sql <- dbEscapeString(con, tmp)
dbGetQuery(con, sql)
## End(Not run)

sql <- dbEscapeString(con, tmp)
should be:
sql <- dbEscapeStrings(con, tmp)
