Hide/Show Plugin Menu options to Role based

Hi,

I am developing a plugin, in that plugin, based on user selection the plugin should display the plugin mmenus or options to all users or restricted users.

I tried by using for administrator only
add_menu_page('id', 'name', 'administrator', basename(__FILE__), 'call_back');
worked fine and I tried changed administrator to read, edit_posts, worked perfectly.

But when I tried to get the user input using get_option and based on the get_option the capability will vary, for example user selected the plugin menu should display to all users including subscribers. It should be
add_menu_page('id', 'name', 'read', basename(__FILE__), 'call_back');

So I tried like this,
0 – Administrator
1 – edit posts
2 – read

First I get the user value using get_option() and based on the option I tried,

If($value==0)
$valueee=administrator;
elseif($value==1)
$valueee=edit_posts;
elseif($value==2)
$valueee=read;
add_menu_page('id', 'name', '$valueee', basename(__FILE__), 'call_back');

After using like this it is not working 🙁

Kindly suggest me
