[R] Need help

fk5 ~. is a formula, most likely used by a regression (or similar model). 
fk5 is the response variable, and the dot is a placeholder for 'whatever 
was on that side of the formula before'.  (This is usually used for 
updating models.)  list() places the formula in a list, obviously.  It's 
hard to provide more meaning without the context.

(Also, mailing list etiquette suggests you should provide a more 
informative subject line than 'need help'.)
