htaccess help!

[ian]

I've set the following htaccess redirects to cover off all instances of non-https, as well as any potential 404 errors, but I want all traffic to go to www. if the url is typed without. Can someone help!

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
ErrorDocument 404 https://MYURL
