I am using R Studio for creating plots for economic variables. But in our language when you don't use our specific letters as "ğ,ş,ı,ü,ç" the word means different. And even sometimes it means swearing. I can't create graphs with this letters. I tried to use this command;
Sys.setlocale(category = "LC_ALL", locale = "Turkish")
The output is
OS reports request to set locale to "Turkish" cannot be honored[1] ""
How can i solve this problem? Any idea?
