You could ask for HTML help on fitted, but don't use the class print method:

 > unclass(?fitted)
[1] 
"/Library/Frameworks/R.framework/Versions/3.4/Resources/library/stats/help/fitted.values"
attr(,"call")
help(topic = "fitted", package = NULL)
attr(,"topic")
[1] "fitted"
attr(,"tried_all_packages")
[1] FALSE
attr(,"type")
[1] "html"

The first line says that the name should be "fitted.values".
